● Siv: tetramethylurrea yog siv los ua kev siv tshuaj ntsuam nyob rau hauv dyestuff kev lag luam, hauv kev tawm tsam hws thiab cuam tshuam hauv surfactant. Nws tau siv rau lub hauv paus catalyzed isomerization thiab alkylation hydrocyanation vim nws qhov kev tso cai tsawg. Nws reacts nrog oxalyl chloride los npaj tetramethyl cloroformamidinium cov kua qaub thiab cov pheeb suab thiab pyrophosphates feem.
1,1,3,3-tetramethylurea, tseem hu ua TMU lossis N, N ', n'-tetramethylureA, yog cov tshuaj lom neeg nrog cov mis molecular c6h14n2o. Nws yog cov khoom siv crystalline uas yog soluble heev hauv dej thiab lwm yam polar solvents.tmu tau dav siv los ua cov kuab tshuaj thiab reagent nyob rau ntau yam tshuaj lom neeg. Nws cov solubility siab thiab cov kuab lom tsawg ua nws cov kuab tshuaj uas nyiam nyiam xws li cov txheej txheem rho tawm, thiab ua cov tshuaj tiv thaiv nruab nrab rau cov organic synthesis. Nws kuj tseem siv tau los yaj cov urea derivatives, TMU tuaj yeem ua rau nws muaj txiaj ntsig ntau yam kev hloov tshuaj. Nws yog ib txwm ua haujlwm hauv peptide synthesis, hlau-catalyzed cov kev tawm tsam, thiab raws li cov tshuaj tiv thaiv nruab nrab hauv kev tshawb fawb.
