Selelekela

1,9-Nonanediol ke diol e nang le liathomo tse robong tsa carbon. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 1,9-nonanediol:

 

Boleng:

1,9-Nonanediol ke e tiileng e nang le likristale tse tšoeu mocheso oa kamore. E na le litšobotsi tsa ho hloka 'mala, ho hloka monko, le ho qhibiliha ka har'a metsoako ea tlhaho e kang metsi, ether le acetone. Ke motsoako o sa fetoheng 'me o na le chefo e tlaase.

 

Sebelisa:

1,9-Nonanediol e na le lisebelisoa tse ngata indastering ea lik'hemik'hale. E ka sebelisoa e le solvent le solubilizer, hape e ka sebelisoa ho tsa meriana, lidae, li-resin, liphahlo, li-plastiki le liindasteri tse ling. E na le thepa e ntle ea surfactant 'me e ka boela ea sebelisoa e le emulsifier, e kenyang metsi le stabilizer.

 

Mokhoa:

Ho na le litsela tse 'maloa tsa ho lokisetsa 1,9-nonanediol,' me e 'ngoe ea mekhoa e sebelisoang hangata ke synthesis ho tloha karabelo ea hydrogenation ea nonanal. Nonanal e sebetsana le haedrojene boteng ba "catalyst" ho hlahisa 1,9-nonanediol.

 

Lintlha tsa Tšireletseho:

1,9-Nonanediol e na le chefo e tlaase 'me e sireletsehile bakeng sa tšebeliso ea indasteri. Joaloka ntho ea lik'hemik'hale, mehato e latelang ea tšireletso e ntse e lokela ho hlokomeloa:

- Qoba ho kopana le letlalo le mahlo. Ha u kopana, hlatsoa hang-hang ka metsi a mangata 'me u buisane le ngaka.

- Nakong ea tšebeliso, moea o motle o lokela ho sebelisoa ho qoba ho hema likhase kapa mouoane.

- Ha u boloka le ho tšoara, e lokela ho sireletsoa hore e se ke ea kopana le li-oxidants le lintho tse matla tsa oxidizing ho qoba mollo kapa ho phatloha.

- Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka liatlana, likhalase le liaparo tsa ts'ireletso nakong ea ts'ebeliso.
