Lihlahisoa
Isopropyl joala CAS No. 67-63-0
Tlhaloso ea Sehlahisoa
DEG e hlahisoa ke karolo ea hydrolysis ea ethylene oxide. Ho itšetlehile ka maemo, palo e fapaneng ea DEG le li-glycols tse amanang le tsona li hlahisoa. Sehlahisoa se hlahisoang ke limolek'hule tse peli tsa ethylene glycol tse kopantsoeng ke tlamo ea ether.
"Diethylene glycol e tsoa e le sehlahisoa se kopantsoeng le ethylene glycol (MEG) le triethylene glycol. Ka kakaretso indasteri e sebetsa ho eketsa tlhahiso ea MEG. Ethylene glycol ke boholo bo boholo ka ho fetisisa ba lihlahisoa tsa glycol ka mefuta e sa tšoaneng ea lisebelisoa. Ho fumaneha ha DEG. e tla itšetleha ka tlhokahalo ea lihlahisoa tsa sehlahisoa sa mantlha, ethylene glycol, ho fapana le litlhoko tsa mmaraka tsa DEG."
