Nhanganyaya
Dimethylmalonic acid (inozivikanwawo se succinic acid) inhengo yeorganic. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza dimethylmalonic acid:
Hunhu:
- Kuonekwa: Dimethylmalonic asidhi inowanzova isina ruvara crystalline kana chena poda.
- Solubility: Soluble mune zvakajairika zvinonyungudutsa semvura, ethanol uye ether.
Shandisa:
- Seyakagadzirwa maindasitiri: Inogona kushandiswa kugadzira polyester resins, solvents, coatings uye glues.
Nzira:
- Nzira yakajairika yekugadzirira dimethylmalonic acid inowanikwa ne hydroformylation ye ethylene additive. Nhanho chaiyo ndeye hydrogenate ethylene ine formic acid kuti igadzire glycolic acid, uye woenderera mberi nekuita esterification pakati peglycolic acid uye formic acid kuti uwane yekupedzisira chigadzirwa dimethylmalonic acid.
Zvekuchengetedza
- Dimethylmalonic acid haina chepfu, asi kutarisirwa kunofanirwa kutorwa kutevera nzira dzakachengeteka dzekushanda murabhoritari uye panzvimbo yekugadzira.
- Dzivirira kufemerwa neguruva kana kubata neganda nemaziso paunenge uchiishandisa, uye pfeka giya rekudzivirira rakakodzera (semuenzaniso, magirovhosi nemagirazi).
- Muchiitiko chekusangana netsaona, sukurudza nzvimbo yakakanganiswa nekukurumidza nemvura yakawanda uye tsvaga rubatsiro rwekurapa kana zvichidikanwa.
