Gabatarwa

1,3-Dicarboxymethyl-2-methyl-2-thioisourea, wanda kuma aka sani da DDMTU, wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga yanayinsa, amfaninsa, hanyar shiri da bayanin aminci:

inganci:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea fari ko rawaya crystalline m. Yana da kwanciyar hankali mai kyau a zafin jiki kuma ana iya narkar da shi a cikin wasu kaushi na polar, kamar ruwa, barasa da ketones.

Amfani:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea ana amfani dashi ko'ina a cikin haɗin gwiwar kwayoyin halitta azaman ingantaccen fili na thiomoded. Yana iya haifar da oxidation na sulfide kamar thioether, thionitrile da thiamine don samar da mercaptans masu dacewa, thioketones da imines.

Hanya:

Hanyar shiri na 1,3-dicarboxymethyl-2-methyl-2-thioisourea ya ƙunshi matakai biyu: amsawar thioglycolic acid tare da methylisourea don samun 1,3-dicarboxymethyl-2-methyl-2-thioisourea; Ana tsarkake samfurin da aka yi niyya ta hanyar crystallization ko wasu hanyoyin tsarkakewa.

Bayanin Tsaro:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea ba shi da wata cutarwa ga jikin mutum da muhalli a ƙarƙashin yanayin aiki na yau da kullun. Yakamata a kula don gujewa haduwa da fata kai tsaye da shakar kurarta yayin aiki. Yakamata a yi aiki da shi a cikin kyakkyawan yanayi kuma a guji shakar tururinsa. Ka guji amsawa da abubuwa kamar oxidants, acid mai ƙarfi, da tushe mai ƙarfi. Lokacin adanawa da sarrafa shi, ya kamata a ajiye shi a cikin busasshen busasshen, iskar da iska kuma ba ta da iska, nesa da wuta da tushen zafi. Da fatan za a koma zuwa bayanan aminci masu dacewa da umarnin aiki yayin amfani.
