Tom qab chlorination lossis nev ntawm nws, ntau yam anthraquinone dyes tuaj yeem ua ke. Txheeb xyuas cov txheeb cais tau qhia tias muaj ntau pua ntawm Istraquinone dyes, uas muaj tus nqi lag luam zoo
(2) Nws tuaj yeem siv rau hauv cov txheej txheem papermakaking:
2- ishenanthraquraquinoyog ib qho khoom qab zoo heev. Nws tuaj yeem nkag mus rau hauv lub sab hauv ntawm cov ntoo ntoo thiab raug txo rau nws. Nws tsis ruaj khov thiab yooj yim rau oxidize. Nyob rau hauv no redox puag, cov khoom siv hauv cov chips ntoo yog oxidized, uas int intensifies cov tshuaj tiv thaiv thiab txhim kho cov kev ua tau zoo ntawm pulping.
2-} Methylanthraiquino yog ib qho tseem ceeb organic thiab muaj cov khoom siv raw nrog ntau cov ntawv thov.
1. Kev npaj ntawm cov siab kawg thiab cov intermediates:
Nws nyob qhov tseem ceeb ntawm txoj haujlwm tseem ceeb hauv kev lag luam Dow, thiab ua ib qho tseem ceeb organic nruab nrab, nws tuaj yeem siv los ua syesize thiab intermediates. Nyob rau hauv cov nqe lus ntawm dispersed dyes, lawv tuaj yeem siv los ua ke nrog kev ua tsis tau zoo nrog kev ua tau zoo, uas muaj ntau cov ntawv thov hauv Textile Printing thiab Dyeing. Vim yog lawv cov xim ntau nrawm, thiab ib puag ncig cov phooj ywg, xws li dav siv nyob rau hauv ntau cov fibers, xws li polyester, nylon, thiab acrylic. Nyob rau hauv cov nqe lus ntawm acidic dyes, lawv tuaj yeem siv los ua ke synthesize dyes, xws li acidic mordant dyes thiab acidic Printing pastes. Cov dyes no muaj cov ntawv thov dav hauv cov liaj teb xws li Tawv Dyeing thiab Textile Printing. Acid Dyes muaj cov xim ci, muaj xim zoo nkauj, ua rau lawv haum rau Dyeing thiab luam ntawv hauv acidic media. Nyob rau hauv cov nqe lus ntawm kev txo qhov tuag, lawv tuaj yeem siv los ua ke ua ke txo qis, xws li txo cov xiav dyes thiab txo cov ntsuab dyes.

2. Pulp sib ntxiv hauv cov txheej txheem papermaking:
Cov txheej txheem papermaking yog qhov tsis tseem ceeb ntawm kev tsim khoom, thiab cov pulping txheej txheem yog qhov txuas tseem ceeb hauv cov txheej txheem papermakaking. Hauv cov txheej txheem no, ntau yam ntxiv yog xav tau los txhim kho kom zoo thiab ua tau zoo ntawm daim ntawv. Raws li ib qho txuj ci tseem ceeb ntxiv, nws yog siv dav hauv kev lag luam papermaking.
Firstly, cov tshuaj no tuaj yeem txhim kho lub pulping efficiency. Hauv cov txheej txheem ib txwm muaj, muaj cov tshuaj thiab cov rog ntau dua yog qhov yuav tsum tau hloov cov khoom siv roj fiber ntau rau hauv pulp. Txawm li cas los xij, cov txheej txheem no tsis muaj txiaj ntsig thiab siv ib qho tseem ceeb ntawm lub zog thiab peev txheej. Los ntawm kev ntxiv 2- ishylanthraiquino, lub zog kev noj haus nyob rau hauv cov pulping txheej txheem tuaj yeem raug txo kom zoo, thiab lub pulping efficiency tuaj yeem hloov kho.
Thib ob, kev siv nws tuaj yeem txhim kho cov ntawv zoo. Thaum lub sij hawm lub sam thiaj, cov khoom siv xws li hnav cov tsiaj txhu thiab cov khaub ncaws ntim hauv cov khoom siv raw tuaj yeem cuam tshuam rau lub zog thiab dawb ntawm daim ntawv. Yog tias cov khoom siv no tsis meej, qhov zoo ntawm daim ntawv yuav cuam tshuam. Nws tuaj yeem hloov kho cov impurities, txhim kho lub zog thiab dawb ntawm daim ntawv, thiab yog li txhim kho cov ntawv zoo.
Tsis tas li ntawd, siv 2- ethylanthraiquraquinone ua tau tus pulping additive kuj tuaj yeem txo cov tshuaj lom neeg siv. Hauv cov txheej txheem tsoos tsho, muaj cov tshuaj lom neeg ntau xws li acids, alkalis, yuav tsum tau kho cov khoom siv roj raw fiber ntau. Qhov kev siv tshuaj ntau dhau ntawm cov tshuaj no tsis yog nce nqi, tab sis kuj ua rau muaj kuab paug rau ib puag ncig. Los ntawm kev siv nws, kev siv ntawm cov tshuaj no tuaj yeem raug txo kom tsawg, yog li txo cov nqi tsim khoom thiab ib puag ncig pa paug.

Cov ntaub ntawv ntawm Metric Cov Menyuam Hluav Taws Xob Sprocket
Los ntawm kev kuaj txoj kev, {{}} ishylanthraquride yog synthesis ua kom zoo rau kev txhim kho cov txiaj ntsig ntawm cov khoom lag luam.
1. Toluene thiab Phthalic Anhydrid Strivriv yauv ua rau cov tshuaj tiv thaiv kab mob hauv lub pob zeb Aluminium ntawm Alharichloride:
C6H5C6H5 + C8H6O3 + Alcl3 → C6H5Lub zog loj6H5 + Alcl4-
2. MBBA dehydrates nyob rau hauv concentrated sulfuric acid los tsim nws:
C6H5Lub zog loj6H5 + H2Yog li4 → C14H8O + H2O
Ntawm lawv, () sawv cev ntawm methyl pab pawg hauv toluene; Cov pab pawg ua haujlwm sawv cev rau phthalic anhydride; Sawv cev txhuas trichloride; Sawv cev rau cov sulfuric acid; Sawv cev rau generated 2- Methylanthraquinone.
Kev sim ua ntej:
Qhov kev sim no yog raws li cov qauv ntawm kev tawm tsam acylation, siv cov tshuaj pleev ib ce los ua cov tshuaj tua kab mob phlalicic los ua cov phtalylenthlride los tsim cov khoom siv phthlenlenthl) benzoic acid (MBBA). Tom qab, MBBA undergoes kaw-lub voj tsim ntawm nws nyob rau hauv kev txiav txim ntawm sulfuric acid.
Kev sim ua kauj ruam:
1. Cov ntaub ntawv nyoos thiab reagents:
Toluene, phthalic anhydride, txhuas trichloride, concentrated sulfuric acid, chloroethane (raws li tshuaj tiv thaiv nruab nrab).
01
2. Khoom cua ntawm 2- (4'-methylbenzoyl) benzoic acid (MBBA):
Toluene thiab phthalic anhydride tau ntxiv rau cov tshuaj tiv thaiv flask thiab rhuab mus rau 50 degree. Maj mam ntxiv aluminium trichhloride thiab do rau 4 teev kom hnov. Tom qab cov tshuaj tiv thaiv tau ua tiav, qhov catalyst tau sib cais los ntawm kev siv hluav taws xob kom tau crude MBBA.
02
3. Khoom cua ntawm 2- Methylanthraquinone:
Sib tov crude mbba nrog concentrated sulfuric acid, ua kom sov rau 130 degree, thiab yauv tua lub cev kaw-lub voj voos ntawm chloroethanethane nruab nrab. Tom qab nruam stirring rau 3 teev, txias rau chav kub.
03
4. Cov khoom sib cais thiab huv:
Muab cov tshuaj tiv thaiv cov tshuaj tiv thaiv kom cais 2- methylanthraquraqurine. Tom qab ntau cov kev rho tawm thiab kev ua haujlwm kom huv, ib tug kuj yog nws tau.
04
5. Cov khoom lag luam tau txais thiab cov cim:
Cov qauv ntawm cov khoom lag luam tau cim los ntawm melting taw tes ntsuas kev ntsuas, thiab lwm txoj hauv kev kom paub meej tias cov khoom yog {}} ishylanthraqurine.

Nyob rau hauv cov txheej kev lag luam, lub teeb thaiv kev npaj kho tsev npaj tau npaj los ntawm eceytylanthraquino vim nws cov huab cua sab nraud vim nws cov huab cua zoo heev. Hom txheej no muaj peev xwm tiv taus ultraviolet hluav taws xob tau ntev, tswj hwm cov xim thiab cov choj ntawm kev tsim kho tsev xws li, duab puab, thiab lwm yam. Piv txwv li, qee qhov skyscrapers niaj hnub teeb tsa los ntawm nws cov tsev sab nrauv kom tswj tau lub hnub ci ntsa iab thaum txij nkawm lub voj voog ntawm lub tsho tiv no.
Hauv kev lag luam hauv Ink, cov khoom siv duab duab, cov khoom siv duab duab uas muaj nws tau siv los ua cov khoom tseem ceeb rau kev tsim cov inks zoo. Cov inks tuaj yeem nthuav tawm kev daws teeb meem zoo thiab cov xim kev kos duab zoo li cov ntawv sau ua yeeb yam, thiab lwm yam nthuav tawm cov khoom siv muag heev thiab ntev ntev. Ib qho ntxiv, vim lawv cov nrawm nrawm nrawm nrawm nrawm dua, cov inks tau siv dav hauv cov luam ntawv ntawm kev luam ntawv thiab kev txhim kho cov nqi.
Nyob rau hauv daim teb nplaum, cov resins tshwj xeeb synthesized nrog nws tau tsim mus rau hauv high-ua cov nplaum muaj cov nplaum ua vim lawv cov adhesion zoo heev. Cov nplaum no tsis tsuas yog tsim cov nplaum kom muaj zog ntawm ntau yam li hlau, tab sis kuj tseem tswj tau qhov chaw hnyav xws li kub thiab huab cua siab. Yog li ntawd, lawv tau siv dav hauv qhov chaw sib koom ua ke hauv kev lag luam xws li kev lag luam hauv tsheb, thiab hluav taws xob, ua kom muaj zog ntawm cov khoom lag luam thiab kev ntseeg tau ntev ntawm cov khoom.
Ib qho ntxiv, daim ntawv thov ntawm 2- ishylanthraquino Los ntawm kev siv cov kab ke ntawm cov duab uas muaj cov compound no, cov khoom siv kho qhov tseem ceeb rau kev txhim kho qib siab xws li optoelectRonic zaub thiab kev sib txuas lus kho. Nyob rau tib lub sijhawm, cov kev ua yeeb yam no tseem siv los tsim cov cuab yeej optis optis tsim rau cov khoom lag luam qib siab xws li cov soob thiab micro / nano kev ua.
