2 4-Dichloro-3-Methylbenzoic acid (CAS# 83277-23-0)
Selelekela
3-Methyl-2,4-dichlorobenzoic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
- Ponahalo: E tiileng ka kristale e se nang 'mala
- Sollubility: e qhibilihang ka har'a lihlapolli tsa lintho tse phelang tse kang ethanol, ether le methylene chloride, e ke keng ea qhibiliha ka metsing.
Sebelisa:
- Likokoana-hloko: 3-methyl-2,4-dichlorobenzoic acid ke sebolayalehola se sephara se ka sebelisoang ho laola ho mela ha mefuta e fapaneng ea lehola, joalo ka joang bo potolohileng lijalo tse kang khale, legumes le poone.
Mokhoa:
3-Methyl-2,4-dichlorobenzoic acid e ka lokisoa ka chlorination ea p-methylanise ether (3-methylanisole). Mokhoa o khethehileng oa ho itokisa o ka kenyelletsa mehato e latelang:
Qhala 3-methylanisole ka anhydrous hydrochloric acid.
Sodium chlorite (NaClO) kapa potassium chlorite (KClO) e ile ea kenngoa e le mehloli ea chlorine.
Motsoako oa karabelo o tsosoa ka mocheso o tlase, hangata lipakeng tsa 0-5 °C.
Kamora hore karabelo e phetheloe, motsoako oa tlhotloa kapa oa ntšoa ho fumana sehlahisoa sa 3-methyl-2,4-dichlorobenzoic acid.
Lintlha tsa Tšireletseho:
- 3-Methyl-2,4-dichlorobenzoic acid e ka baka kotsi tikolohong, 'me tlhokomelo e lokela ho lefshoa ho laola tšebeliso le ho lahla litšila.
- Ho kopana ka kotloloho le ntho e itseng ho ka halefisa letlalo, mahlo le tsamaiso ea ho hema, 'me ho kopana ka kotloloho ho lokela ho qojoa.
- Apara lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana, likhalase le limaske ha u sebelisoa.
- Tlhokomelo e lokela ho nkoa ho thibela ho tsoakana le lik'hemik'hale tse ling nakong ea polokelo le ho tšoara, le ho qoba ho khantša le mocheso o phahameng.
- Ka kopo bala 'me u latele lipampiri tse nepahetseng tsa polokeho le litataiso tsa ts'ebetso pele u li sebelisa.
