Selelekela

Asiti ea Fumaric. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea transbutalic acid:

 

Boleng:

- Transbutadiic acid ke kristale e se nang 'mala kapa e tšoeu e tiileng e nang le tatso e bolila e bolila.

- E qhibiliha ka metsing le lihlapolli tse ngata tsa tlhaho tse kang joala le ethers.

- Ka mocheso o phahameng, acid ea transbutylic e senyeha ho hlahisa carbon dioxide le acetone.

 

Sebelisa:

- E sebelisoa haholo ha ho etsoa li-resin tsa polyester bakeng sa ho etsa lihlahisoa tse kang liphahlo, lipolasetiki le likhoele.

 

Mokhoa:

- Transbutenedic acid e ka fumanoa ka karabelo ea brominated butene le sodium carbonate. Mokhoa o ikhethileng oa ho kopanya o kenyelletsa mehato e mengata, ho kenyelletsa ho lokisoa ha butene, karabelo ea bromination, le alkaline hydrolysis.

 

Lintlha tsa Tšireletseho:

- Transbutadiic acid ke motsoako o halefisang o ka bakang ho halefa le ho chesa ha o kopana le letlalo le mahlo.

- Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka liatlana, likhalase le liaparo tsa ts'ireletso ha u li tšoara.

- Qoba ho hema lerole kapa mouoane oa eona 'me e lokela ho sebetsa sebakeng se nang le moea o motle.

- Melao ea lehae le mekhoa e sireletsehileng ea ts'ebetso e lokela ho lateloa ha ho boloka le ho sebetsana le motsoako.
