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

Intshayelelo

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea, eyaziwa nangokuthi i-DDMTU, i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

Umgangatho:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea iyikristale emhlophe okanye ephuzi. Inozinzo oluhle kwiqondo lokushisa kwaye inokunyibilika kwezinye izinyibilikisi zepolar, ezifana namanzi, utywala kunye neeketones.

Sebenzisa:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea isetyenziswa ngokubanzi kwi-organic synthesis njenge-oxidant esebenzayo ye-thiomoded compound. Inokwenza i-oxidation ye-sulfides efana ne-thioether, i-thionitrile kunye ne-thiamine ukuvelisa i-mercaptans ehambelanayo, i-thioketones kunye ne-imines.

Indlela:

Indlela yokulungiselela i-1,3-dicarboxymethyl-2-methyl-2-thioisourea ikakhulu ibandakanya amanyathelo amabini: ukusabela kwe-thioglycolic acid kunye ne-methylisourea ukufumana i-1,3-dicarboxymethyl-2-methyl-2-thioisourea; Imveliso ekujoliswe kuyo ihlanjululwe nge-crystallization okanye ezinye iindlela zokucoca.

Ulwazi ngoKhuseleko:

I-1,3-Dicarboxymethyl-2-methyl-2-thioisourea ayinayo ingozi ebonakalayo kumzimba womntu kunye nokusingqongileyo phantsi kweemeko eziqhelekileyo zokusebenza. Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa ngokuthe ngqo kwesikhumba kunye ne-inhalation yothuli lwayo ngexesha lokusebenza. Kufuneka iqhutywe phantsi kweemeko zokungena umoya kwaye ugweme ukuphefumla imiphunga yayo. Kuphephe ukusabela ngezinto ezifana ne-oxidants, iiasidi ezomeleleyo, kunye neziseko ezomeleleyo. Xa igcinwe kwaye iphathwa, kufuneka igcinwe kwindawo eyomileyo, engenamoya kwaye engenamoya, kude nomlilo kunye nemithombo yobushushu. Nceda ujonge kumaphepha edatha okhuseleko afanelekileyo kunye nemiyalelo yokusebenza ngexesha lokusetyenziswa.
