Dimethyl azelate(CAS#1732-10-1)

Selelekela

Dimethyl azelaic acid (eo hape e tsejoang e le Dioctyl adipate, DOA) ke motsoako o tloaelehileng oa tlhaho. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

Boleng:

- Ponahalo: Mokelikeli o se nang 'mala ho isa ho o mosehla

- Sollubility: e qhibilihang ka har'a lihlapolli tsa lintho tse phelang, e qhibilihang hanyane ka metsing

- Index ea Refractive: hoo e ka bang. 1.443-1.449

Sebelisa:

- Dimethyl azelarate e sebelisoa haholo-holo e le polasetiki, e nang le polasetiki e ntle le ho hanyetsa serame, 'me e ka eketsa bonolo le ho hanyetsa serame sa polasetiki.

- Hangata e sebelisoa ha ho etsoa lipolasetiki tsa polyvinyl chloride (PVC), rabara ea maiketsetso, li-resin tsa maiketsetso, joalo-joalo, ho ntlafatsa polasetiki le matla a tsona.

- Dimethyl azelaate e ka boela ea sebelisoa e le setlolo, se nolofatsang le se thibelang serame, har'a lintho tse ling.

Mokhoa:

Dimethyl azelaic acid hangata e lokisoa ke karabelo ea esterification ka tsela e latelang:

1. React nonanediol ka adipic acid.

2. Eketsa li-esterifying agents, tse kang sulfuric acid, e le li-catalysts ho esterification reaction.

3. Karabelo e etsoa tlas'a mocheso o loketseng le maemo a khatello ho hlahisa dimethyl azelaate.

4. Sehlahisoa se hloekisoa ka ho eketsehileng ka dehydration, distillation le mehato e meng.

Lintlha tsa Tšireletseho:

- Dimethyl azelaic acid e lokela ho sireletsoa tlas'a maemo a tloaelehileng a tšebeliso le ho qoba ho kopana le letlalo le mahlo.

- Apara lisebelisoa tse nepahetseng tsa ts'ireletso, ho kenyeletsoa ts'ireletso ea phefumoloho le liatlana tse sireletsang, haeba li sebelisoa.

- Tlhokomelo e lokela ho lefshoa sebakeng se nang le moea o motle nakong ea ts'ebetso ho qoba ho hema kapa ho kenngoa ka phoso.

- Nakong ea polokelo le lipalangoang, hoa hlokahala ho thibela ho kopana le li-oxidants, li-acids le lintho tse ling ho qoba likotsi tse kotsi.
