● Siv: Tetramethylurea yog siv los ua cov kuab tshuaj hauv dyestuff industries, hauv cov tshuaj tiv thaiv condensation thiab intermediates hauv surfactant.Nws yog siv rau hauv paus catalyzed isomerization thiab alkylation hydrocyanation vim nws tsis tshua muaj permittivity.Nws reacts nrog oxalyl chloride los npaj tetramethyl chloroformamidinium chloride, uas yog siv rau kev hloov pauv ntawm carboxylic acids thiab dialkyl phosphates rau anhydrides thiab pyrophosphates feem.
1,1,3,3-Tetramethylurea, tseem hu ua TMU los yog N, N, N', N'-tetramethylurea, yog ib qho tshuaj compound nrog cov mis molecular C6H14N2O.Nws yog crystalline khoom uas yog soluble nyob rau hauv dej thiab lwm yam polar solvents.TMU yog dav siv raws li ib tug hnyav thiab ib tug reagent nyob rau hauv ntau yam tshuaj.Nws cov solubility siab thiab tsis tshua muaj toxicity ua rau nws nyiam hnyav nyob rau hauv daim ntawv thov xws li cov txheej txheem rho tawm, catalysis, thiab ua cov tshuaj tiv thaiv nruab nrab rau cov organic synthesis.Nws kuj tseem siv tau los ua kom yaj cov organic tebchaw uas tsis tshua muaj soluble hauv lwm cov kuab tshuaj. Zoo ib yam li lwm cov urea derivatives, TMU tuaj yeem ua raws li hydrogen daim ntawv cog lus pub dawb thiab txais, uas ua rau nws muaj txiaj ntsig zoo hauv ntau yam tshuaj hloov pauv.Nws yog feem ntau ua haujlwm nyob rau hauv peptide synthesis, hlau-catalyzed cov tshuaj tiv thaiv, thiab raws li cov tshuaj tiv thaiv nruab nrab hauv kev tshawb fawb tshuaj.
