Ukusetyenziswa
I-Anhydride ye-Anhydride isetyenziswa njenge-acylating regent kwi-synthesic synthesi. Inokusabela ngotywala, ii-phenols, i-amines, njl njl. I-butyuric anhydride inokusetyenziswa njengempahla engaphantsi kwengubo, idayi kunye neplastiki. I-butyuric anhydride inokulungiswa ngokuphendula i-butyuric acid nge-acetic andddride. Iimeko zokuphendula zihlala ziqhutywa phantsi kweemeko ze-acidic kunye namaqondo obushushu asezantsi. I-butyuric anhydride icaphukise kwaye ihlukumeza kwaye inokubangela ukucaphukisa amehlo, ulusu, iphecana lokuphefumla kunye nenkqubo yokugaya. Ngexesha lokusebenza, ukhathalelo kufuneka luthathelwe ukunqanda ukunxibelelana nolusu kunye namehlo, kwaye uqinisekise ukuba ukusebenza kwenziwa phantsi kwemiqathango efanelekileyo.
Lulwa lungenamibala kwaye lubonakale lulwelo nge-odor engathandekiyo. Ukuxinana kwesihlobo yi-0.9668 (20/20 ℃), indawo yokunyibilika ngu -75 ℃, kwaye inqaku lokubila yi-198 ℃. Inyibilika kwiinyibiliki ezifana ne-ether. Ibolile kwi-butyuri acid xa idibana namanzi. I-iphendula ngotywala ukuze isebenze. Luhlobo olungenamibala, lube lulo olubonakalayo. Inyibiliza emanzini kwaye ibolile ukwenza i-butyric acid, kwaye inyibilikisi kwi-ether.
Ukupakisha kunye nokuhambisa
I-195 kg / idrum okanye njengeemfuno zabathengi.
Yeyokwesi ntlobo zezinto eziqhelekileyo kwaye unokuzisa ulwandle nomoya
Gcina kwaye ugcine
Ubomi beshellofu: inyanga yonke ukusuka kumhla wokwenziwa kwemveliso kwintengiso yentsusa egcinwe kwindawo epholileyo yokukhanya kwelanga, amanzi.
Igumbi lokugcina umoya elinomoya, iqondo lokushisa eliphantsi eliphantsi, elahlulwe kwii-oxidants, acids.
