Thepa ea Sehlahisoa:
1.Mokelikeli o mosoeu kapa o mosehla o bonaletsang hanyane o nang le monko o monate. E qhibilihang ka metsing; ethanol; ether le chloroform, joalo-joalo, e sa tsitsang, e bolileng ha e sebelisana le alkali kapa e hloekisitsoeng ka khatello ea sepakapaka. Ha e tsitsa, e senyeha ha e sebelisana le alkali kapa e silafalitsoeng ka khatello ea sepakapaka.
2.Sehlahisoa se na le chefo e tlaase, ho metsa sehlahisoa ho thibetsoe ka thata, mosebeletsi o lokela ho apara liaparo tse sireletsang.
3. Lintho tsa lik'hemik'hale: Tahi ea Diacetone e na le carbonyl le hydroxyl ka har'a molek'hule, e nang le lik'hemik'hale tsa ketone le joala bo phahameng. Ho bola ho etsahala ha ho futhumatsoa ho 130 ° C kapa ka holimo ka alkali, ho hlahisa limolek'hule tse 2 tsa acetone. Ha e futhumatsoa ka sulfuric acid kapa ho latela palo ea iodine, e ntša metsi ho etsa isopropylidene acetone. Ho sebelisana le sodium hypobromite ho hlahisa 2-hydroxyisovaleric acid. Catalytic hydrogenation e hlahisa 2-methyl-2,4-pentanediol.
4.Sehlahisoa sena se halefisa mahlo, letlalo le li-membrane tsa pampiri ea ho hema. E kena 'meleng ka tsela ea ho hema le ea tšilo ea lijo, e ama tsamaiso ea methapo le ho senya sebete le mpa. Ho hema moea oa mouoane o phahameng ho ka etsa pulmonary edema esita le koma. Ho pepeseha ha nako e telele ho ka lebisa ho dermatitis.
5. E fumanoa ho koae ea ho baka, koae e nang le likhopo tse tšoeu, koae ea linoko le mosi oa sakerete.
Sesebelisoa sa Sehlahisoa:
1.Diacetone joala e ka sebelisoa e le ho hloekisa tšepe, ho boloka lehong, ho boloka filimi ea lifoto le lithethefatsi, antifreeze, solvent for hydraulic fluids, extractant le fiber finishing agent.
2.Diacetone joala e sebelisoa haholo e le solvent bakeng sa electrostatic spray pente, celluloid, nitrocellulose, mafura, oli, boka ba boka le resin. Joala ba diacetone ke mokelikeli oa tlhaho o belang o phahameng. Viscosity e tlase mme phello ea mocheso ho viscosity e nyane. E sebelisoa e le solvent le pente stripper bakeng sa pente ea cellulose ester, enke ea khatiso, pente ea resin ea maiketsetso jj.
3.E sebelisoa haholo e le mokelikeli oa li-resin, lipente tsa electrostatic spray, celluloid, nitro fibers, mafura, oli le boka. E boetse e sebelisoa e le ho hloekisa tšepe, ho boloka lehong, ho boloka filimi ea lifoto le meriana, antifreeze, solvent ea oli ea hydraulic, extractant le fiber finishing agent. Hape ke mofuta oa organic synthesis intermediates.
4.Cosmetic solvent, haholo-holo e sebelisoang e le polisi ea lipekere le litlolo tse ling tsa mokelikeli o phahameng oa ho belisa. Hangata e entsoe ka lintho tse hlapollang tse tlase tse belang le li-solvents tse mahareng tse belang ka har'a metsoako e tsoakiloeng, e le ho fumana sekhahla se nepahetseng sa mouoane le viscosity.
Lintlha tsa polokelo ea Sehlahisoa:
1.E boloke sebakeng sa polokelo se pholileng, se nang le moea o pholileng.
2.Kena hole le mollo le mohloli oa mocheso, qoba khanya ea letsatsi.
3. Boloka setshelo se tiisitsoe.
4.Ha e senyehe ho tšepe, 'me e ka bolokoa ka lijaneng tsa tšepe, tsa tšepe kapa tsa aluminium, empa e na le phello e senyang mefuta e mengata ea polasetiki.
5.Ho boloka le ho tsamaisa ka thoko ho li-oxidising agents le acid.
6.Bakete ea tšepe kapa botlolo ea khalase e tletse lintho tse entsoeng ka lepolanka.
