Synthetic Hom ntawm Trithiocarbonate
Oct 24, 2021
Trithiocarbonate yog lub teeb daj daj thiab yog cov khoom siv tshuaj lom neeg.
Kev ua haujlwm ntawm thiocarbonyl pawg hauv cov qauv trithiocarbonate tuaj yeem ua kom ntseeg tau qhov kev vam meej ntawm cov saw hlau hloov cov tshuaj tiv thaiv, txo qis kev cuam tshuam, thiab muaj kev cuam tshuam me ntsis ntawm cov xim ntawm cov khoom polymer, thiab tseem tuaj yeem tswj kev npaj cov khoom siv polymer nrog cov qauv sib txawv, thiab lwm yam. Yog li ntawd, nws cov synthesis yog kev txhawj xeeb los ntawm cov kws tshawb fawb txog kev sib raug zoo.
Synthesis ntawm trithiocarbonate Cov txheej txheem qhia ntxov tshaj plaws ntawm trithiocarbonate feem ntau suav nrog cov hauv qab no: mercaptan thiab thiophosgene cov tshuaj tiv thaiv, trithiocarbonate sodium ntsev thiab alkyl halide cov tshuaj tiv thaiv, aryl chloro mercaptan Cov tshuaj tiv thaiv nrog alkyl mercaptan tebchaw, benzene mercaptans thiab reacts nrog CS2 theem ntawm alkyl halide. hloov catalysts, thiab lwm yam. Cov tshuaj tiv thaiv no muaj ntau yam tsis txaus, xws li cov txheej txheem sib xyaw ua ke, nyuaj kom tau txais cov khoom siv raw, lub sijhawm ntev cov tshuaj tiv thaiv, qhov kub thiab txias yuav tsum tau, ntau cov tshuaj lom lossis cov ntxhiab tsw ntxhiab reagents, cov khoom lag luam tsawg, thiab tsim los ntawm- cov khoom uas tsis paub cov qauv. (xws li sulfide) thiab lwm yam. Tom qab ntawd, tom qab kev tshawb nrhiav, ntau yam tshiab, me me, thiab ib puag ncig tus phooj ywg hluavtaws tau tsim ib qho tom qab.
