Nhanganyaya
Furoyl acetate, inowanzozivikanwa seacetylsalicylate, inhengo yemubatanidzwa. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza furfuryl acetate:
Hunhu:
Furfuryl acetate imvura isina ruvara kune yakachenuruka yero ine kunhuhwirira kwakakosha. Inonyungudika mumhando dzakasiyana-siyana dzeorganic solvents, senge madoro uye ether, pamhepo tembiricha.
Zvishandiso: Iine kunhuhwirira kwemuchero uye inowanzoshandiswa mukunhuhwirira uye zvinonhuwira kuwedzera kunhuhwirira uye kuravira kwechigadzirwa. Furfur acetate inogona zvakare kushandiswa mumaindasitiri ekushandisa senge machira, mapurasitiki uye rabha.
Nzira:
Furfur acetate inowanzogadzirirwa ne esterification reaction, iyo chaiyo mashandiro ndeyekuita furfuric acid ine acetic anhydride, kuwedzera esterification catalysts senge sulfuric acid kana ammonium formate, uye kuita pane imwe tembiricha nenguva. Pakupera kwekuita, tsvina inobviswa nekupera mvura uye distillation kuti uwane yakachena furfuryl acetate.
Zvekuchengetedza
Furfuryl acetate ine yakaderera chepfu, asi kufema kwenguva refu kunogona kuve nemhedzisiro yehutano husina kunaka. Furfur acetate imvura inopfuta uye inofanirwa kuchengetedzwa kure nemirazvo yakavhurika uye yakanyanya tembiricha masosi, uye inochengetwa munzvimbo inotonhorera, ine mhepo. Teerera matanho ekudzivirira panguva yekushandiswa, sekupfeka magirazi ekudzivirira, magirovhosi ekudzivirira uye zvipfeko zvekudzivirira. Kana pakadeuka kana kuti muchetura, tora matanho erubatsiro rwekutanga nekukurumidza uye tsvaga kurapwa nenguva.
