Nhanganyaya
1,3-Dicarboxymethyl-2-methyl-2-thioisourea, inozivikanwawo seDDMTU, inhengo yehupenyu. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
1,3-Dicarboxymethyl-2-methyl-2-thioisourea ichena kana yero yekristaro yakasimba. Iine kugadzikana kwakanaka pakupisa kwekamuri uye inogona kunyungudutswa mune dzimwe polar solvents, semvura, doro uye ketone.
Shandisa:
1,3-Dicarboxymethyl-2-methyl-2-thioisourea inoshandiswa zvakanyanya muorganic synthesis sechinhu chinoshanda thiomoded compound oxidant. Inogona kukonzeresa oxidation ye sulfides senge thioether, thionitrile uye thiamine kugadzira inoenderana mercaptans, thioketones uye imines.
Nzira:
Nzira yekugadzirira ye1,3-dicarboxymethyl-2-methyl-2-thioisourea inonyanya kusanganisira matanho maviri: maitiro etioglycolic acid ane methylisourea kuwana 1,3-dicarboxymethyl-2-methyl-2-thioisourea; Chigadzirwa chinonangwa chinocheneswa necrystallization kana dzimwe nzira dzekuchenesa.
Zvekuchengetedza
1,3-Dicarboxymethyl-2-methyl-2-thioisourea haina kukuvadza kuri pachena kumuviri wemunhu uye zvakatipoteredza pasi pemamiriro ekushanda. Kuchengetedza kunofanira kutorwa kuti usapinda zvakananga neganda uye inhalation yeguruva rayo panguva yekushanda. Inofanirwa kushandiswa pasi pemamiriro emhepo inofefetera zvakanaka uye kudzivirira kupinza mhute yayo. Dzivisa kuita zvinhu zvakaita semaoxidants, maasidhi akasimba, uye mabhesi akasimba. Kana yachengetwa uye yabatwa, inofanira kuchengetwa mumudziyo wakaoma, unofefeterwa uye usingapindi mhepo, kure nemoto nekupisa. Ndokumbira utarise kune akakodzera kuchengetedza data mapepa uye mirairo yekushandisa panguva yekushandiswa.
