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

Isingeniso

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea, eyaziwa nangokuthi i-DDMTU, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

Ikhwalithi:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea iyikristale eqinile emhlophe noma ephuzi. Inokusimama okuhle ekamelweni lokushisa futhi ingancibilika kwezinye izincibilikisi ze-polar, ezifana namanzi, utshwala nama-ketones.

Sebenzisa:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea isetshenziswa kabanzi ku-organic synthesis njenge-oxidant esebenzayo ye-thiomoded. Ingakwazi ukuvuselela i-oxidation yama-sulfide afana ne-thioether, i-thionitrile ne-thiamine ukukhiqiza ama-mercaptan ahambisanayo, ama-thioketones nama-imines.

Indlela:

Indlela yokulungiselela ye-1,3-dicarboxymethyl-2-methyl-2-thioisourea ngokuyinhloko ihlanganisa izinyathelo ezimbili: ukusabela kwe-thioglycolic acid nge-methylisourea ukuthola i-1,3-dicarboxymethyl-2-methyl-2-thioisourea; Umkhiqizo ohlosiwe ube usuhlanzwa nge-crystallization noma ezinye izindlela zokuhlanza.

Ulwazi Lokuphepha:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea ayinawo umonakalo osobala emzimbeni womuntu kanye nemvelo ngaphansi kwezimo ezijwayelekile zokusebenza. Ukunakekelwa kufanele kuthathwe ukuze ugweme ukuthintana ngqo nesikhumba kanye nokuhogela uthuli lwaso ngesikhathi sokusebenza. Kufanele isetshenziswe ngaphansi kwezimo ezinomoya omuhle futhi igweme ukuhogela umhwamuko wayo. Gwema ukusabela ngezinto ezifana nama-oxidants, ama-asidi aqinile, nezisekelo eziqinile. Uma igcinwe futhi isingathwa, kufanele igcinwe esitsheni esomile, esingena umoya futhi esingangeni moya, kude nomlilo nemithombo yokushisa. Sicela ubheke amashidi edatha okuphepha afanele kanye nemiyalelo yokusebenza ngesikhathi sokusebenzisa.
