Isingeniso

I-Dodecyl alcohol, eyaziwa nangokuthi i-dodecyl alcohol noma i-dococosanol, iyinhlanganisela yezinto eziphilayo. Iqinile, ayinambala futhi ayinaphunga nephunga elikhethekile.

 

I-Dodecyl alcohol inezici ezilandelayo:

2. Ayincibiliki emanzini, kodwa incibilika kuzincibilikisi zemvelo njenge-ether notshwala.

3. Inokuqina okuhle nokuguquguquka okuphansi.

4. Inezinto ezinhle zokugcoba futhi ingasetshenziswa njengesithambiso.

 

Ukusetshenziswa okuyinhloko kwe-dodecyl alcohol kufaka okulandelayo:

1. Njengento yokugcoba, isetshenziselwa ukugcoba imishini nemishini yezimboni.

2. Njengempahla eluhlaza yama-surfactants, ingasetshenziswa ukulungisa izinto zokuhlanza nezihlanzi.

3. Njenge-solvent ne-diluent yodayi noyinki.

4. Isetshenziswa njengempahla eluhlaza yezinambitheka zokwenziwa, evame ukusetshenziswa ekwenzeni amakha namakha.

 

Indlela yokulungiselela i-dodecyl alcohol ingahlanganiswa ngezindlela ezilandelayo:

1. I-Hydroreduction of stearate catalyzed by potassium hydroxide.

2. Ngokusabela kwe-hydrogenation ye-dodecene.

 

1. Nakuba i-dodecyl alcohol iyinhlanganisela ephephile uma kuqhathaniswa, isadinga ukugcinwa ivalwe ngokuqinile futhi igweme ukuthintana nomoya-mpilo ukuze kuvinjelwe i-oxidation.

2. Gwema ukusabela okunodlame ngama-oxidants aqinile nama-asidi.
