Taw qhia
Acetone aldehyde dimethanol, tseem hu ua acetone methanol. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm acetone aldehyde dimethanol:
Zoo:
Acetone aldehyde dimethanol yog xim tsis muaj xim rau cov kua daj daj nrog cov ntxhiab tsw. Nws yog ib qho organic compound uas yog soluble hauv dej, cawv, thiab ethers. Acetone aldoldehyde methanol tsis ruaj khov, yooj yim hydrolyzed thiab oxidized, nws yuav tsum tau muab cia rau hauv qhov chaw txias thiab tsaus, thiab khaws cia kom deb ntawm cov pa oxygen, cua sov thiab hluav taws xob.
Siv:
Acetone aldoldehyde dimethanol feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv rau hauv kev npaj ntawm esters, ethers, amides, polymers, thiab qee cov organic tebchaw. Pyrudaldehyde methanol kuj tseem siv los ua cov kuab tshuaj, tus neeg sawv cev ntub dej thiab cov khoom ntxiv hauv cov txheej txheem thiab cov khoom lag luam yas.
Txoj kev:
Muaj ntau txoj hauv kev los npaj acetone aldehyde dimethanol. Ib txoj hauv kev yog tau los ntawm cov tshuaj tiv thaiv condensation ntawm methanol nrog acetone. Hauv kev npaj, methanol thiab acetone yog sib xyaw ntawm ib qho piv txwv molar thiab reacted nyob rau hauv lub xub ntiag ntawm acidic catalyst, uas feem ntau yuav tsum tau cua sov cov tshuaj tiv thaiv sib tov. Tom qab cov tshuaj tiv thaiv tiav lawm, ntshiab acetone aldoldehyde dimethanol yog tau los ntawm distillation, crystallization los yog lwm txoj kev sib cais.
Cov ntaub ntawv kev nyab xeeb:
Acetone aldoldemic methanol yog ib qho ua rau khaus khaus thiab yuav tsum tsis txhob cuam tshuam ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab cov mucous membranes. Kev ua pa zoo yuav tsum tau ua thaum lub sijhawm ua haujlwm, thiab cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav. Thaum tuav thiab khaws cia, lub thawv yuav tsum tau muab kaw kom zoo kom deb ntawm tshav kub, ignition thiab oxidants. Yog noj los yog nqus tau, nrhiav kev kho mob tam sim ntawd.
