Nhanganyaya
Triacetaldehyde. Izvi zvinotevera sumo pfupi kune chimiro chayo, kushandiswa, nzira yekugadzira uye ruzivo rwekuchengetedza.
Hunhu:
Acetaldehyde ipfumbu isina ruvara kune yakachenuruka yecrystalline poda ine kuravira kunotapira.
Huremu hwayo hwemamorekuru hunosvika 219.27 g/mol.
Patembiricha yemumba, triacetaldehyde inonyungudika mumvura, methanol, ethanol uye ether solvents. Ichaora pakupisa kukuru.
Shandisa:
Acetaldehyde inogona zvakare kushandiswa mukugadzirira kwezvinhu zvemagetsi, resin modifiers, fiber flame retardants uye mamwe maindasitiri minda.
Nzira:
Acetaldehyde inogona kuwanikwa ne acid-catalyzed polymerization yeacetaldehyde. Iyo chaiyo nzira yekugadzirira yakaoma, inoda mamwe mamiriro ekuyedza uye catalysts, uye kazhinji inoda kuita pa100-110 ° C.
Zvekuchengetedza
Acetaldehyde inogona kunge iine muchetura uye inotsamwisa kumuviri wemunhu pane imwe nzvimbo, uye kungwarira kunofanirwa kutorwa kudzivirira kusangana kwakananga neganda, maziso uye nzira yekufema kana uchiishandisa.
Paunenge uchisangana nemoto, polyacetaldehyde inopfuta uye inofanira kuchengetedzwa kure nemirazvo yakavhurika uye tembiricha yakakwira.
Paunenge uchishandisa kana kuchengetedza triacetaldehyde, nzvimbo ine mhepo yakanaka inofanirwa kuchengetedzwa uye kure neoxidizing agents.
Pakubata meretaldehyde, pfeka zvinodzivirira zvakakodzera senge magirovhosi, magirazi ekudzivirira, uye masks ekudzivirira.
