Kushandiswa
Butyric anhydride inonyanya kushandiswa se acylating reagent mu organic synthesis. Inogona kuita ne alcohols, phenols, amines, nezvimwewo kuti igadzire ma esters anoenderana, phenyl ethers, amides nezvimwe zvinhu. Butyric anhydride inogonawo kushandiswa sechinhu chisina kugadzirwa chekuputira, madhayi nemapurasitiki. Butyric anhydride inogona kugadzirwa nekuita butyric acid ne acetic anhydride. Mamiriro ekuita anowanzoitwa mumamiriro ezvinhu ane acidic uye patembiricha yakaderera. Butyric anhydride inotsamwisa uye inoparadza uye inogona kukonzera kutsamwa kumaziso, ganda, nzira yekufema uye kugaya. Panguva yekuvhiyiwa, kungwarira kunofanira kutorwa kudzivirira kusangana neganda nemaziso, uye kuve nechokwadi chekuti kuvhiyiwa kwacho kunoitwa mumamiriro ezvinhu ane mhepo yakanaka.
Imvura isina ruvara uye inopenya ine hwema husina kunaka. Kuwanda kwayo kuri 0.9668 (20/20℃), kunyunguduka kuri -75℃, uye kufashaira kuri 198℃. Inonyunguduka muzvinhu zvinonyunguduka zvakaita se ether. Inoora kuita butyric acid kana yasangana nemvura. Inosangana nealcohols kuita ma esters. Imvura isina ruvara, inopenya uye inobvira moto. Inonyunguduka mumvura uye inoora kuita butyric acid, uye inonyunguduka mu ether.
Kurongedza uye Kutumira
195 kg/dhiramu kana zvichienderana nezvinodiwa nemutengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
