Intshayelelo

I-Dodecyl alcohol, eyaziwa ngokuba yi-dodecyl alcohol okanye i-dococosanol, yi-organic compound. Iqinile, ayinambala kwaye ayinavumba kunye nevumba elikhethekileyo.

 

I-Dodecyl alcohol ineempawu ezilandelayo:

2. Ayinyibiliki emanzini, kodwa inyibilika kwizinyibilikisi eziphilayo ezifana ne-ether kunye notywala.

3. Unozinzo oluhle kunye nokuguquguquka okuphantsi.

4. Ineempawu ezilungileyo zokuthambisa kwaye inokusetyenziswa njenge-lubricant.

 

Ukusetyenziswa okuphambili kwe-dodecyl alcohol kubandakanya oku kulandelayo:

1. Njenge-lubricant, isetyenziselwa ukuthambisa izixhobo zoshishino kunye noomatshini.

2. Njengempahla ekrwada yee-surfactants, ingasetyenziselwa ukulungisa izinto zokucoca kunye nezokucoca.

3. Njenge-solvent kunye ne-diluent kwiidayi kunye neenki.

4. Isetyenziswa njengento ekrwada yokwenza iziqholo ezenziweyo, ehlala isetyenziswa ekwenzeni iziqholo neziqholo.

 

Indlela yokulungiselela i-dodecyl alcohol inokudityaniswa ngezi ndlela zilandelayo:

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

2. Ngokusabela kwe-hydrogenation ye-dodecene.

 

1. Nangona i-dodecyl alcohol iyikhompawundi ekhuselekileyo, isafuna ukugcinwa ivalwe ngokuqinileyo kwaye igweme ukudibanisa ne-oxygen ukukhusela i-oxidation.

2. Gwema ukuphendula ngobundlobongela kunye nee-oxidants ezinamandla kunye neeasidi.
