Mawu Oyamba
Furoyl acetate, yemwenso amadziwika kuti acetylsalicylate, ndi organic pawiri. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha furfuryl acetate:
Ubwino:
Furfuryl acetate ndi madzi achikasu mpaka otumbululuka okhala ndi fungo lapadera. Amasungunuka m'mitundu yosiyanasiyana ya organic solvents, monga ma alcohols ndi ether, kutentha kwapakati.
Ntchito: Ili ndi fungo lonunkhira bwino la zipatso ndipo nthawi zambiri imagwiritsidwa ntchito muzokometsera ndi zonunkhira kuti iwonjezere fungo ndi kukoma kwa mankhwalawa. Furfur acetate itha kugwiritsidwanso ntchito pamafakitale monga zokutira, mapulasitiki ndi mphira.
Njira:
Furfur acetate nthawi zambiri imakonzedwa ndi esterification reaction, ntchito yake ndikuchita furfuric acid ndi acetic anhydride, kuwonjezera zopangira esterification monga sulfuric acid kapena ammonium formate, ndikuchita pa kutentha kwina ndi nthawi. Pamapeto pa zomwe zimachitika, zonyansa zimachotsedwa ndi kutaya madzi m'thupi ndi distillation kuti mupeze furfuryl acetate yoyera.
Zambiri Zachitetezo:
Furfuryl acetate ili ndi kawopsedwe kakang'ono, koma kupuma kwanthawi yayitali kumatha kukhala ndi zotsatira zoyipa zaumoyo. Furfur acetate ndi madzi oyaka moto ndipo amayenera kusungidwa kutali ndi malawi otseguka komanso kutentha kwambiri, ndikusungidwa pamalo ozizira komanso mpweya wabwino. Samalani njira zodzitetezera mukamagwiritsa ntchito, monga kuvala magalasi oteteza, magolovesi oteteza komanso zovala zodzitchinjiriza. Pakatayikira kapena poyizoni, chitani njira zoyenera zothandizira nthawi yomweyo ndipo pitani kuchipatala munthawi yake.
