Nyob rau tib lub sijhawm, ntxiv 0.2-0.5% ntawm propyl decanolactone rau cov ntxhua khaub ncaws thiab cov ntaub softener tuaj yeem txhim kho qhov kev paub ntawm cov khoom.
Feed flavoring agent: ib qho tshuaj ntxiv uas ua rau cov tsiaj noj ntau ntxiv
Raws li tus neeg sawv cev pub khoom noj khoom haus, propylene glycol lactone tuaj yeem txhawb cov tsiaj olfactory qab haus huv, txhim kho kev noj zaub mov zoo, thiab txhawb kev loj hlob:
Npua noj
Ntxiv 10-30mg / kg ntawm propyl decanolactone rau piglet pub tuaj yeem nce kev noj zaub mov los ntawm 15-20% thiab qhov hnyav txhua hnub nce los ntawm 8-12%. Nws cov txheej txheem ntawm kev txiav txim yog simulate lub qab zib aroma ntawm mis niam thiab alleviate weaning stress.
Ruminant tsiaj pub
Ntxiv propylene decanolactone rau nyuj concentrate tshuaj tuaj yeem ua rau kom cov khoom qhuav kom tsawg li 5-8% thiab txhim kho cov mis nyuj rog. Kev sim cov ntaub ntawv qhia tau hais tias ntxiv 20mg / kg ntawm caprylic acid tuaj yeem ua rau cov kua mis ntau ntxiv hauv cov nyuj los ntawm 1.2kg / hnub.
Tsiaj noj
Hauv cov khoom noj miv thiab dev, thaum ua ke nrog cov poov xab extract, nws tuaj yeem tsim cov nqaij los yog ntses. Ib hom khoom noj tsiaj tsiaj tau nce nws qhov kev yuav khoom rov qab los ntawm 25% los ntawm kev ntxiv 0.05% propylene glycol lactone.
Kev lag luam kws tshuaj: kev siv ua tshuaj intermediates lossis excipients
Txawm hais tias nws daim ntawv thov nyob rau hauv kws tshuaj yog tseem nyob rau hauv nws cov me nyuam mos,hydroxydecanoictau pom muaj peev xwm tus nqi:
Tshuaj intermediates
Raws li ib qho tseem ceeb raw khoom rau synthesizing anticancer tshuaj thiab tshuaj tua kab mob, nws muaj peev xwm koom nyob rau hauv hydroxylation cov tshuaj tiv thaiv los tsim cov qauv molecular nrog lom lom. Piv txwv li, nyob rau hauv lub synthesis ntawm paclitaxel sab chains, kev siv ntawm propyl decyl lactone raws li ib tug nitroso qhia tus neeg sawv cev yuav ua rau kom cov purity ntawm cov khoom mus rau 99%.
Pharmaceutical excipients
Hauv kev txhawb nqa - cov qauv tso tawm, nws tuaj yeem siv los ua cov khoom siv txheej txheem los tswj cov tshuaj tso tawm. Nws cov tshuaj lom neeg tsawg thiab biocompatibility ua raws li USP (United States Pharmacopeia) cov qauv thiab tsim nyog rau qhov ncauj capsules thiab ntsiav tshuaj.
Kev Kho Mob Essence
Hauv aromatherapy, nws cov tshuaj tsw qab peach tuaj yeem txo kev ntxhov siab. Kev tshawb fawb soj ntsuam tau pom tias nqus cov roj tseem ceeb uas muaj 0.5% propargyrolactone tuaj yeem txo qis cov tshuaj hormones (cortisol) hauv cov ntsiab lus los ntawm 22%.
Kev lag luam teb: multifunctional kuab tshuaj thiab additives
Daim ntawv thov nyob rau hauv kev lag luam teb yog tsuas yog raws li nws cov khoom hnyav thiab tshuaj stability:
Coatings thiab inks
Raws li ib puag ncig tus phooj ywg hnyav, nws tuaj yeem hloov qee cov organic tebchaw (VOCs) thiab txo cov ntxhiab tsw ntawm txheej. Ntxiv 1-3% ntawm propyl decyl lactone rau UV kho coatings tuaj yeem txhim kho qib thiab txo qhov tsis xws ntawm pinhole.
Adhesive
Raws li ib tug plasticizer nyob rau hauv kub yaj nplaum nplaum thiab siab -sensitive nplaum, nws tuaj yeem txhim kho qhov yooj thiab nplaum lub zog ntawm cov gel. Kev sim tau pom tias qhov sib ntxiv ntawm 2% propyl decyl lactone tuaj yeem ua rau lub zog tev ntawm cov nplaum los ntawm 18%.
Lithium roj teeb electrolyte
Raws li ib qho ntxiv, propyl decyl lactone tuaj yeem tiv thaiv electrolyte decomposition thiab ua rau lub neej ntev roj teeb. Ib txoj kev tshawb fawb qhia tau hais tias ntxiv 0.5% ntawm propyl decanolactone tuaj yeem ua rau kom muaj peev xwm tuav tau ntawm lithium -ion roj teeb rau 92% tom qab 500 cycles.
Txoj kev 1: Artificial synthesis
Siv n-heptanol los teb nrog acrylic acid los yog methyl acrylate nyob rau hauv lub xub ntiag ntawm dawb radical pib los npaj propyl decanolactone. Qhov no yog txoj kev sib txuas ntawm propyl decanolactone uas tuaj yeem tsim loj - nplai ntau lawm tam sim no.
Siv n-heptanol thiab acrylic acid ua cov khoom pib, di tert butyl peroxide ua tus pib, thiab ntxiv cov tshuaj tiv thaiv cov kuab tshuaj, cov khoom nyoos ntawm c-decyl lactone tau tsim los ntawm cov dawb radical ntxiv hauv "ib lub lauj kaub", thiab tom qab ntawd cov tshuaj tiv thaiv hnyav tau rov qab los ntawm distillation, thiab tom qab ntawd cov c-decyl lactone tau npaj los ntawm lactone.
Thaum lub sij hawm no synthesis txheej txheem, los ntawm - cov khoom yuav tsis raug cais tawm ntawm cov tshuaj tiv thaiv nyob rau hauv lub sij hawm, ua rau ib tug txo nyob rau hauv cov tshuaj tiv thaiv tawm los thiab ncua sij hawm cov tshuaj tiv thaiv, Ntxiv mus, cov khoom muaj roj tsw ntawm boiling point impurities, siab boiling point impurities thiab tsis zoo roj noj tsw ntawm isomers, uas cuam tshuam rau aroma zoo ntawm cov khoom kawg ntawm c{1}declactone.
Txoj kev 2: Biocatalysis method
GDL enzyme muaj catalytic kev ua si nyob rau hauv non{0}}aqueous theem thiab yog dav siv nyob rau hauv cov organic synthesis. Lipase yog qhov siv ntau tshaj plaws. Nws yog pheej yig, tsis xav tau coenzyme, thiab muaj zog substrate adaptability.
Lipase tuaj yeem ua rau tsis yog tsuas yog hydrolysis ntawm lipids xwb, tab sis kuj esterification thiab transesterification hauv cov organic theem, suav nrog kev tsim cov lactones los ntawm hydroxyl fatty acids.
Txawm li cas los xij, nws yog ib qho nyuaj heev rau cyclize cov hydroxyl acids los ntawm cov txheej txheem, thiab cov tawm los yog tsawg heev. Nws yog qhov yooj yim dua los ua kom tiav cov txheej txheem cyclization los ntawm cov txheej txheem enzymatic hauv cov organic media, uas tsis muaj qhov xav tsis thoob muab txoj hauv kev zoo rau cov lag luam loj - nplai ntawm cov lactones aromatic.
Qee zaum, yog tias muaj kev tso cai, lwm txoj hauv kev biotechnological enzyme catalysis tuaj yeem siv tau. Nws kuj tseem yuav dhau los ua ib qho tseem ceeb los daws qhov teeb meem ntawm kev lag luam ntawm lactone bioactive tshuaj nyob rau yav tom ntej.
