1 3-bis(methoxycarbonyl) -2-methyl-2-thio-pseudour (CAS# 34840-23-8)

Mawu Oyamba

1,3-Dicarboxymethyl-2-methyl-2-thioisourea, yomwe imadziwikanso kuti DDMTU, ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Ubwino:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea ndi yoyera kapena yachikasu makristalo olimba. Zimakhala zokhazikika bwino kutentha kwa chipinda ndipo zimatha kusungunuka muzitsulo zina za polar, monga madzi, mowa ndi ketoni.

Gwiritsani ntchito:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea imagwiritsidwa ntchito kwambiri popanga organic synthesis ngati thiomoded pawiri oxidant. Itha kuyambitsa makutidwe ndi okosijeni a sulfide monga thioether, thionitrile ndi thiamine kuti apange ma mercaptans, thioketones ndi imines.

Njira:

Njira yokonzekera 1,3-dicarboxymethyl-2-methyl-2-thioisourea makamaka imaphatikizapo masitepe awiri: momwe thioglycolic acid ndi methylisourea ikupeza 1,3-dicarboxymethyl-2-methyl-2-thioisourea; Chotsatiracho chimatsukidwa ndi crystallization kapena njira zina zoyeretsera.

Zambiri Zachitetezo:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea ilibe vuto lililonse mthupi la munthu komanso chilengedwe pansi pazikhalidwe zogwirira ntchito. Care ayenera kumwedwa kupewa mwachindunji kukhudzana ndi khungu ndi inhalation fumbi lake pa ntchito. Iyenera kugwiritsidwa ntchito pansi pa mpweya wabwino ndikupewa kutulutsa nthunzi yake. Pewani kuchitapo kanthu ndi zinthu monga ma okosijeni, ma asidi amphamvu, ndi maziko amphamvu. Ikasungidwa ndi kugwiridwa, iyenera kusungidwa mu chidebe chowuma, chopanda mpweya komanso chopanda mpweya, kutali ndi moto ndi magwero a kutentha. Chonde onani zidziwitso zoyenera zachitetezo ndi malangizo ogwiritsira ntchito mukamagwiritsa ntchito.
