Selelekela

1,1,1-Trifluoroacetone. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:

 

Boleng:

1,1,1-trifluoroacetone ke mokelikeli o tukang o nang le tatso e monate. E tsitsitse haholo ka lik'hemik'hale, ha e bole habonolo ke li-acids, alkalis kapa li-oxidants, 'me ha e na hydrolyzed habonolo. E na le monyetla o motle 'me e qhibiliha mefuteng e fapaneng ea lihlapolli tse kang joala, ethers le ketone.

 

Sebelisa:

1,1,1-Trifluoroacetone e na le mefuta e mengata ea tšebeliso indastering. Ke sehlapolli sa bohlokoa se ka sebelisoang libakeng tse kang lirafshoa, lihloekisi, li-degreaser, le li-sealant tsa khase. E ka boela ea sebelisoa e le moemeli oa ho ruruha bakeng sa polyurethane, polyester le PTFE, hammoho le plasticizer le flame retardant bakeng sa ho roala.

 

Mokhoa:

Tokisetso ea 1,1,1-trifluoroacetone e etsoa haholo-holo ke karabelo ea reagent ea fluorinated e nang le acetone. Mokhoa o tloaelehileng ke ho sebelisa ammonium bifluoride (NH4HF2) kapa hydrogen fluoride (HF) ho itšoara ka acetone boteng ba catalyst ho hlahisa 1,1,1-trifluoroacetone. Ts'ebetso ena ea karabelo e hloka ho etsoa tlas'a taolo e matla hobane hydrogen fluoride ke khase e chefo.

 

Lintlha tsa Tšireletseho:

1,1,1-Trifluoroacetone ke mokelikeli o tukang o ka phatlohang ha o pepesehela lelakabe le bulehileng kapa mocheso o phahameng. E na le flash point e tlase le thempereichara ea autoignition, 'me e hloka ho tšoaroa le ho bolokoa ka nepo, hole le lintho tse tukang le tse chesang. Lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liaparo tse sireletsang mahlo, liatlana le liaparo tse sireletsang li lokela ho apesoa ha li sebelisoa. E lokela ho netefatsoa hore e sebetsa sebakeng se nang le moea o motle le ho qoba ho hema mouoane oa eona kaha o ka baka tšenyo 'meleng oa motho.
