piav qhia luv luv:


Khoom Nthuav dav

Cov khoom lag luam

Ib qho ntawm FURANS nrog carbonyl yog li tsim kev voj voog lactone. Nws yog cov tshuaj tiv thaiv endogenous uas ua los ntawm gamma-aminobutyrate thiab yog tus tsim ntawm gamma-hydroxybutyrate. Nws kuj yog siv los ua tus neeg sawv cev ntawm cov tshuaj thiab cov kuab tshuaj.

Daim ntaub ntawv:
Hauv cov kab mob acidic nws tsim cov khoom sib xyaw ua ke ntawm ob qho sib xyaw. Cov tebchaw no ces txuas mus ua cov polymer. Thaum kho nrog lub hauv paus tsis-nucleophilic, zoo li lithium diisopropylamide, Butyrolactone tuaj yeem dhau los ua alpha-carbon nucleophile. Cov ntsig ntsig txog caprolactone tuaj yeem siv los ua cov polyester hauv no.

Butyrolactone tsis ua haujlwm ntawm nws tus kheej txoj cai; nws mechanism ntawm kev txiav txim stems los ntawm nws tus kheej li ib tug prodrug ntawm.
Cov nyhuv hypnotic yog kho kom zoo los ntawm kev sib xyaw nrog cawv. Kev tshawb nrhiav nas 2003 qhia tias Butyrolactone ua ke nrog ethanol tsom pom muaj lub zog ua rau lub zog hypnotic, raws li kev ntsuas lub sijhawm pw ntev dua li ob qho tib si ntawm cov khoom sib xyaw ua ke.

Butyrolactone yog cov ua kom tsis haum rau ua kom pom cov kua roj ua kom muaj roj. Nws tuaj yeem xyaw nrog dej thiab yaj los ntawm ethanol ether, benzene thiab acetone. Nws tuaj yeem yaj ntau lwm cov organic thiab inorganic compound. Siv Butyrolactone muaj kev nyab xeeb thiab yooj yim, vim tias nws yog kua nrog kub npau npau, muaj peev xwm muaj peev xwm, muaj cov khoom siv hluav taws xob zoo thiab kev nyab xeeb. Nws yog tsuas yog siv los ua hluavtaws pyrolidone series khoom cyclopropylamine acetyl-r-butyrolactone, dua li cov no, Butyrolactone kuj tseem siv ua kuab tshuaj rau kev ua liaj ua teb chemical, polymer, dyestuff thiab luam ntawv. Siv butyrolactone ua cov khoom siv raw, peb tuaj yeem tsim cov tshuaj tsw qab, tshuaj ntsuab tshuaj lom neeg thiab xeb tshem tawm.

Effect-Butyrolactone Cov teebmeem:
Ua rau kev so.
Ua rau lub hlwb meej.
Pab daws kev nyuaj siab thiab kev ntxhov siab.
Lub neej ua haujlwm ntev.
Txhim kho kev sib deev thiab ua kev lom zem.
Txo cov rog.
Txhim kho kev ua kis las.
Txhim kho kev pw tsaug zog.
Raws li lub cev tsim qauv lossis ua kom nqaij pob txha.
Raws li cov tshuaj ua si.

1) Nws tuaj yeem siv los coj los ua cov khoom pyrrolidone;
2) Nws tuaj yeem siv los ua cov tshuaj nruab nrab hauv nruab nrab, xws li Cyclopropylamine thiab vitamin;
3) Nws tuaj yeem raug siv ua tshuaj tua kab nruab nrab, xws li tshuaj tua kab thiab kev cog kev cog kev cog ntoo;
4) Nws tuaj yeem siv rau alkenes, alkynes extraction tus neeg sawv cev, nqus dej thiab dispersing tus neeg sawv cev;
5) Nws tuaj yeem siv los ua hluavtaws ua cov tshuaj tiv thaiv kabmob, yas ua kom zoo, ua kom tus neeg tawg tawm, txhim kho tus neeg sawv cev thiab txhim kho;
6) Nws tuaj yeem siv los coj los ua kom muaj fiber ntau spinning hnyav, coagulant, dyeing tus pabcuam thiab tus sawv cev antistatic;
7) Nws tuaj yeem raug siv los ua cov khoom siv ntawm cov xim zaj duab xis qub, electrolyte, capacitor thiab roj nplua nyeem.
