Selelekela
Monomethyl dodecanedioate, eo hape e tsejoang e le octylcyclohexylmethyl ester, ke motsoako oa lintho tse phelang.
Boleng:
- Ponahalo: Monomethyl dodecanedioate hangata e fumanoa e le mokelikeli o se nang 'mala.
- Solubility: E qhibiliha ka har'a lihlapolli tsa tlhaho tse kang joala, ethers le ketone.
- Sebaka sa ho tima: Hoo e ka bang 127°C.
Sebelisa:
- Monomethyl dodecanedioate ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse tala, tse atisang ho sebelisoa ha ho etsoa litlolo tse sebetsang hantle le litlolo tse sebetsang hantle haholo.
- E ka boela ea sebelisoa e le polasetiki bakeng sa lipolasetiki le rabara, e ntlafatsa ho fetoha ha tsona le ho sebetsa habonolo.
- Monomethyl dodecanedioate e ka boela ea sebelisoa e le lisebelisoa tse tala bakeng sa motsoako oa manyolo, joalo ka ho lokisa lidae, li-fluorescents, li-melting agents le li-plasticizers.
Mokhoa:
Ho lokisoa ha monomethyl dodecanedioate hangata ho etsoa ka mehato e latelang:
1. Eketsa dodecanedioic acid le methanol ho reactor.
2. Karabelo ea esterification mochesong o loketseng le khatello hangata li hloka boteng ba catalyst joalo ka sulfuric acid kapa hydrochloric acid.
3. Ka mor'a ho fela ha karabelo, sehlahisoa se aroloa 'me se hloekisoa ka ho sefa kapa ho senya.
Lintlha tsa Tšireletseho:
- Qoba ho hema, ho kopana le letlalo le mahlo. Lisebelisoa tse loketseng tsa tšireletso tse kang liatlana, likhalase tse sireletsang, le liaparo tse sireletsang li lokela ho apesoa nakong ea ts'ebetso.
- Qoba ho kopana le li-oxidizing tse matla nakong ea polokelo le lipalangoang ho qoba mollo le ho phatloha.
- Ha o sebetsana le ho lahla litšila, ikamahanye le melao le melawana e amehang, 'me u lahlele litšila ka nepo.
