Ib Leeg Diisoproyl phosphite Cas 1809-20-7

Shaanxi Bloom Tech Co., Ltd. yog ib qho ntawm cov neeg tsim khoom lag luam thiab cov neeg muag khoom ntawm di@opropyl phosphite CAS 1809-20-7 nyob rau hauv Suav teb. Txais tos rau kev lag luam wholesale tej yam zoo diisopropyl phosphite CAS 1809 -20-7 rau muag ntawm no los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab tus nqi tsim nyog muaj.

Diisopropyl phospepitePuas yog cov kua dej tsis muaj kob ntawm cov tshuaj c6h15o3p thiab cas 1809 -}} 7. Corrosive, soluble hauv ethanol thiab lwm yam kuab tshuaj organic. Diisopr phosprof yog tshwj xeeb tshuaj tua kab tsis zoo, uas tuaj yeem siv los npaj cov organophosphorid thoo o organophophlyl thia orgiopropyl thio (dej cawv) ammonium phosphate. Nrog nws cov qauv tshuaj tshwj xeeb cov qauv thiab kev cuam tshuam, nws tau dhau los ua tus choj tseem ceeb txuas tshuaj tua kab, tshuaj, thiab cov ntaub ntawv kawm tshuaj. Nrog rau kev txhim kho ntawm Green Technises thiab precision synthesis thev naus laus zis, lawv cov kev siv hauv lub neej muaj kev lag luam tseem ceeb ntxiv rau kev txhim kho kev lag luam thoob ntiaj teb.

Diisopropyl phospepite(Cov mis nyuj C6h15o3p, tus lej lej 1809 -}}}}} Nws yog cov pob tshab thiab tsis muaj xim ntawm chav sov thiab yog soluble hauv dej thiab feem ntau cov kuab tshuaj. Cov phosphorus atom nyob rau hauv nws cov qauv molecular muaj nyob rau hauv +3 Valence xeev, thiab ob pab pawg neeg hydroxyl (- Oh) tso nws nrog refucity. Vim nws cov tshuaj tshwj xeeb, cov compound no tau pom cov ntawv thov uas muaj nuj nqis uas muaj cov tshuaj tua kab, tshuaj, thiab cov khoom siv tshuaj ntsuam.

Cov ntawv thov tseem ceeb hauv kev ua liaj ua teb

 

1. Khoom cua ntawm organophosphorus fungicide ikidacloprid
Nws yog ib qho tseem ceeb hauv nruab nrab rau kev tsim cov organic phosphorus fungide, yos yidawen Jing. Nws txoj hauv kev hluavtaws cuam tshuam nrog cov neeg caij tsheb ciav hlau nrog cov kab mob A, cov cawv) Ammonoprthe (dej cawv) ammon rov qab mus rau isopyruve acid. Ua ib qho kev lom zem ua hauj lwm, Yidao Wenjing muaj cov kab mob fungal thiab yog dav siv nyob rau thaj chaw ntawm Asia.

Txhim kho ntawm cov txheej txheem hluavtaws:

Tsoos txoj kev: Siv phosphorus trichloride (pcl ignoride (pcl α) thiab isopropanol raws li cov ntaub ntawv raw, diisopropyl phosphit yog tsim los ntawm cov tshuaj tiv thaiv esterification nyob rau hauv Benzene cov kuab tshuaj. Cov tshuaj tiv thaiv kub yuav tsum tau tswj hwm ntawm 40- 60℃kom tsis txhob tsim cov khoom ntawm cov khoom lag luam.

 

Txhim kho cov txheej txheem: roj av ether (30-60 degree) yog siv los ua cov kuab tshuaj, thiab cov tshuaj carbonate ntxiv ua cov aciding tus neeg sawv cev. Nyob rau hauv nitrogen tiv thaiv, cov tshuaj tiv thaiv tawm tuaj yeem ncav cuag 87% thiab kev coj dawb huv tshaj 99%. Cov qauv no txo ​​kev siv cov kuab tshuaj lom thiab yog nyob rau hauv txoj kab nrog cov qauv ntawm cov khoom siv ntsuab.

2. Anti Hnav Cov Khoom Siv Roj Quav Ntxiv
Tom qab sib sau ua haujlwm diisoproofsy nrog triphernof thiophone tshuaj, nws tuaj yeem siv los ua kev tiv thaiv ntawm T8 steel / Al ₂ O3 Ceramics. Nws cov tshuab kev ua yog tias phosphorus lub ntsiab lus tsim cov tshuaj yeeb yaj kiab ua yeeb yaj kiab nrog cov hlau saum npoo av, txo cov kev sib txhuam. Kev sim cov ntaub ntawv qhia tau tias kev ntxiv 5% diisoprochly tuaj yeem txo cov hnav los ntawm 40%, ua rau haum rau lubricating siab siab thauj cov tshuab.

Kev tsim kho lub rooj tsavxwm hauv thaj chaw ntawm cov tshuaj

 

1. Khoom cua ntawm intermediates nyob rau sab qab teb sab saw ntawm etapepti
Etapenem yog qhov dav - spectrum carbapiot, thiab synthesis ntawm nws sab saw intermedia n} - diisopropylphosphorphosphorphosphosphosphosphosphosphosphosphosphosphosphosphosphosphosesx Trans - 4 {- hydroxy {}}}}} priisopropyl phosphat. This process adopts phase transfer catalysis technology, using 4R-hydroxy-L-proline as raw material, reacting with diisopropyl phosphit under alkaline conditions, and then adding a mixed solution of sodium hypochlorite/sodium hydroxide dropwise to complete oxidation. Qhov zoo dua ntawm hom no yog tias:

Cov tshuaj tiv thaiv me me: tsis tas yuav tsum tau tswj qhov kub thiab txias tsis nruj, tuaj yeem ua tiav ntawm chav sov;
Cov qoob loo siab: cov kev coj dawb huv ntawm cov khoom lag luam nce mus txog 98%, thiab cov txiaj ntsig ntau dua 85%;

 

Yooj yim rau kev khiav lag luam: Ib lub lauj kaub cov tshuaj tiv thaiv txo cov kauj ruam sib nrug sib cais, haum rau kev lag luam ntau lawm.

2. Kev loj hlob ntawm cov tshuaj tiv thaiv tshuaj tsis zoo
Huangshi Fuertai Kws Tshuaj Siv Khoom Siv Technology Technology Technology Technology Technology Testivize ntawm Tenofoviry of Tenofoviry of Tenofoviry of Tenofovir (A Anti Hiv Cov Tshuaj Siv) SivDiisopropyl phospepiteCov. Hauv nws txoj kev hluavtaws, diiscropyl phosphit ua raws li cov tshuaj phosphorpating ua rau cov khoom lag luam nucleosidated, uas yog tom qab ntawd oxidized thiab hydrolyzed kom tau txais lub hom phiaj nruab nrab. Cov txheej txheem no tau txhim kho kev xaiv thiab txo qis tiam ntawm lom los ntawm - cov khoom.

Muaj nuj nqi nthuav dav nyob rau hauv cov ntaub ntawv txuj ci

 

1. Nto Kev Hloov Kho ntawm Cov Ntaub Ntawv Ceramic
Diisopr phosphit tuaj yeem tsim cov phosphoryl hloov txheej nyob rau ntawm ib qho chaw ntawm kev tso zis siv tshuaj lom neeg nruab nrab ntawm Ceramics thiab Hlau Charmet. Cov kev sim tau pom tias cov khoom siv cov khoom siv sib xyaw ua ke muaj 30% nce ntxiv hauv kev cuam tshuam shear muaj zog, ua rau nws muaj kev lag luam siab.

2. Cov khoom ua ntej rau cov khoom hluavtaws ntawm Optoelectronic cov ntaub ntawv
Hauv kev txhim kho cov - emeds} emeds), diisoproocescent compents xws li iRidium thiab platinum los ua cov khoom siv luminanced. Nws tau txais txiaj ntsig zoo nyob rau hauv lub zog hluav taws xob pub cov khoom ntawm cov khoom phosphoryL, uas tuaj yeem hloov kho lub zog nruab nrab ntawm cov hlau thiab txhim kho lub luminescence efficiency ntawm lub cuab yeej.

Cov ntsiab lus kev ua haujlwm hauv kev lag luam

 

1. Tswj ntawm cov txheej txheem hluavtaws tsis zoo
Cov khoom siv raw: thaum cov nyiaj maum mos ntawm phosphorus trichloride rau isopropanol yog 1: 2.2, tus nqi Esterification yog qhov siab tshaj plaws;
Kev xaiv catalyst catalyst cov organiccawv (xws li Pyridine organic (xws li nrawm qhov tshuaj tiv thaiv, tab sis cov nyiaj yuav tsum tau tswj kom tsis txhob sab kev sib raug zoo;
Cov kauj ruam kev tshaj tawm: Tom qab ua plaub ntawm dej tshauv, nws xav tau sib cais thiab lim dej los ntawm lub tshuab nqus tsev (siab<10mmHg), with a boiling point range of 72-75 ℃ (10mmHg).

 

2. Kev khaws cia thiab kev nyab xeeb
Stability: ruaj khov nyob rau hauv cov huab cua qhuav, tab sis decomposes rau hauv phosphine (muaj kev lom zem heev) thiab phosphoric acid thaum sib chwv dej;
Cov tshuaj tsis sib thooj: cov oxidants muaj kuab (xws li potassium permanganate) thiab muaj zog acids (xws li muaj cov sulfuric acid) tuaj yeem ua rau muaj kev kub ntxhov;
Kev tiv thaiv kev tiv thaiv: Hnav daim npog roj (en149 txuj ci), cov hnab looj tes tiv thaiv (en13034 txuj ci (ua los ntawm nitrile roj hmab) thaum lub sijhawm ua haujlwm.

Txhawm rau txhim kho cov txiaj ntsig thiab kev nyab xeeb ntawmDiisopropyl phospepite, cov txheej txheem kev nruam cov chaw ntawm cov txheej txheem ntawm diisopropyl tau kawm siv phosphoride thiab isopropanol raws li cov ntaub ntawv raw. Cov kev cuam tshuam ntawm deacidification mob, hnyav, cov tshuaj tiv thaiv, cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv ntawm cov kev tawm tsam tau tshawb xyuas lub sij hawm yog 20 degree, thiab cov tshuaj tiv thaiv lub sijhawm tau 5 xyoos piv nrog Cov txheej txheem ib txwm ua, cov hlau microchannel cov tshuaj tiv thaiv cov txiaj ntsig, txo cov nqi ua haujlwm, thiab txhim kho cov khoom lag luam tsim khoom ruaj khov thiab kev nyab xeeb.

Cov txheej txheem npaj yog txhawm rau rov qab ncaj qha isopropanol nrog phosphorus trichhloride kom tauDiisopropyl phospepite.

3 (ch₃)₂Choh + pcl₃→ [(CH₃)₂Rua]₂Poh +2 hc ↑ + (ch₃)₂Chcl

Cov isopropanol yog kev pub tsis tu ncua ntawm tus nqi ntawm 215 kg / h thiab phosphorus trichloride ntawm tus nqi ntawm 150 kg / h [tus piv yog 3: 1 (MchemalbookOol)]. Tom qab sib tov, nws reatercts ua txhaum. Lub hydrogen chloride gas tsim tawm tau sai sai tawm los ntawm cov laujking sib xyaw los ntawm lub tshuab mercury. Tus neeg nplua roj tsim yog rhuab nyob rau hauv lub caij nplooj zeeg zaj duab xis hom viav vias phaj deacidififier. Tus thawj mob dagically txuas ntxiv mus. Lub deagidifier tawm ntawm qhov kub ntawm 120 ~ 130℃thiab txias rau hauv qab 40 degree. Ntawd yog, cov khoom siv nrog cov ntsiab lus ntawm 92% ~ 95% yog tau, nrog cov txiaj ntsig ntawm 95% ~ 98%.
