Khoom Properties:
1.Dawb los yog daj me ntsis pob tshab kua uas muaj ntxhiab tsw. Soluble hauv dej; ethanol; ether thiab chloroform, thiab lwm yam., tsis ruaj khov, decomposed thaum interacting nrog alkali los yog distilled ntawm atmospheric siab. Nws tsis ruaj khov, decomposes thaum cuam tshuam nrog alkali lossis distilled ntawm atmospheric siab.
2.Cov khoom muaj toxicity tsawg, nqos cov khoom yog nruj me ntsis txwv tsis pub, tus neeg teb xov tooj yuav tsum hnav cov iav tiv thaiv.
3.Chemical zog: Diacetone cawv muaj carbonyl thiab hydroxyl nyob rau hauv lub molecule, nrog rau cov tshuaj muaj pes tsawg leeg ntawm ketone thiab tertiary cawv. Decomposition tshwm sim thaum nws rhuab mus rau 130 ° C los yog siab dua nrog alkali, ua 2 molecules ntawm acetone. Thaum rhuab nrog sulfuric acid los yog kab ntau ntawm iodine, nws dehydrates tsim isopropylidene acetone. Kev sib cuam tshuam nrog sodium hypobromite tsim 2-hydroxyisovaleric acid. Catalytic hydrogenation tsim 2-methyl-2,4-pentanediol.
4.Cov khoom no irritates lub qhov muag, daim tawv nqaij thiab mucous daim nyias nyias ntawm lub pa ib ntsuj av. Nws nkag mus rau hauv lub cev los ntawm kev ua pa thiab digestive ib ntsuj av, cuam tshuam rau lub paj hlwb thiab ua rau lub siab thiab lub plab. Inhalation ntawm high concentration ntawm vapor tuaj yeem ua rau pulmonary edema thiab txawm coma. Ntev mus ntev yuav ua rau dermatitis.
5.Pom nyob rau hauv cov luam yeeb ci, luam yeeb dawb, luam yeeb, thiab luam yeeb.
Khoom siv:
1.Diacetone cawv tuaj yeem siv los ua cov khoom siv hlau, cov khoom siv ntoo, cov khoom siv rau cov duab thaij duab thiab cov tshuaj, tshuaj tua kab mob, cov kuab tshuaj rau cov kua dej hydraulic, cov extractant thiab fiber ntau tiav.
2.Diacetone cawv yog dav siv los ua ib qho hnyav rau cov tshuaj pleev xim electrostatic, celluloid, nitrocellulose, rog, roj, waxes thiab resins. Diacetone cawv yog lub siab kub kub ntawm cov organic hnyav. Lub viscosity tsawg thiab qhov cuam tshuam ntawm qhov kub ntawm viscosity yog me me. Siv ua hnyav thiab xim stripper rau cellulose ester xim, luam ntawv number case, hluavtaws resin xim thiab lwm yam.
3.Widely siv los ua ib qho hnyav rau resins, electrostatic tsuag xim, celluloid, nitro fibers, rog, roj thiab waxes. Nws kuj yog siv los ua hlau ntxuav, ntoo preservative, preservative rau yees duab zaj duab xis thiab tshuaj, antifreeze, hydraulic roj hnyav, extractant thiab fiber xov xov. Nws kuj yog ib hom organic synthesis intermediates.
4.Cosmetic hnyav, feem ntau yog siv los ua ntsia thawv polish thiab lwm yam tshuaj pleev ib ce ntawm lub siab boiling point hnyav. Feem ntau yog tsim nrog cov kuab tshuaj qis-boiling point thiab nruab nrab-boiling point solvents rau hauv cov kuab tshuaj sib xyaw, thiaj li yuav tau txais qhov tsim nyog evaporation tus nqi thiab viscosity.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov, tsis txhob tshav ntuj ncaj qha.
3. Khaws lub thawv kaw.
4.Nws tsis yog corrosive rau hlau, thiab tuaj yeem khaws cia rau hauv cov hlau, mos hlau lossis txhuas ntim, tab sis nws muaj cov nyhuv erosive rau ntau hom yas.
5. Khaws thiab thauj hauv kev sib cais los ntawm oxidising cov neeg ua haujlwm thiab cov kua qaub.
6.Iron thoob los yog iav lub raj mis yog ntim nrog ntoo thawv hauv ob sab phlu khoom.
