Nhanganyaya
Acetone aldehyde dimethanol, inozivikanwawo seacetone methanol. Inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza acetone aldehyde dimethanol:
Hunhu:
Acetone aldehyde dimethanol imvura isina ruvara kusvika kune yero uye inonhuwa. Iyo organic compound inonyungudika mumvura, doro, uye ethers. Acetone aldoldehyde methanol haina kugadzikana, nyore hydrolyzed uye oxidized, inoda kuchengetwa munzvimbo inotonhora uye ine rima, uye kuchengetwa kure neokisijeni, kupisa uye kupisa masosi.
Shandisa:
Acetone aldoldehyde dimethanol inowanzoshandiswa sepakati mune organic synthesis. Inogona kushandiswa mukugadzirira kweesters, ethers, amides, mapolymers, uye mamwe maoriki emakemikari. Pyrudaldehyde methanol inoshandiswawo sechinhu chinonyungudutsa, chekunyorova uye chinowedzera mumaindasitiri emakabati uye epurasitiki.
Nzira:
Pane nzira dzakawanda dzekugadzirira acetone aldehyde dimethanol. Nzira yakajairika inowanikwa ne condensation reaction ye methanol ine acetone. Mukugadzirira, methanol uye acetone zvinosanganiswa pane imwe molar ratio uye inopindirana pamberi peiyo acidic catalyst, iyo inowanzoda kupisa musanganiswa wekuita. Mushure mekuita kwapera, yakachena acetone aldoldehyde dimethanol inowanikwa ne distillation, crystallization kana dzimwe nzira dzekuparadzanisa.
Zvekuchengetedza
Acetone aldoldemic methanol isanganiswa inogumbura uye inofanirwa kudzivirirwa yakanangana neganda, maziso, uye mucous membranes. Kufefetera kwakanaka kunofanirwa kuitwa panguva yekushanda, uye magirovhosi ekudzivirira uye magirazi anofanira kupfekwa. Pakubata nekuchengetedza, mudziyo unofanirwa kuvharwa zvakanaka kure nekupisa, kupisa uye oxidants. Kana ukamwiwa kana kufemerwa, tsvaga kurapwa nekukasika.
