Umsebenzi
I-Buthric Anhydride isetshenziswa ikakhulukazi njenge-reagent eguqukayo ekuhlolweni kwe-organic. Kungasabela ngotshwala, ama-phenols, amine, njll. Ukuze kwakha ama-esters ahambisanayo, izithathi zePhenyl, azide kanye nezinye izinhlanganisela. I-Butyric Anhydride nayo ingahle isetshenziswe njengento eluhlaza yezimbali, udayi namapulasitiki. I-Butyric Anhydride ingalungiswa ngokuphendula i-butyric acid nge-acetic anhydride. Izimo zokuphendula zivame ukwenziwa ngaphansi kwezimo ze-acidic nasemazingeni okushisa aphansi. I-Butyric AnyDride iyacasula futhi iyawa phansi futhi ingadala ukucasuka emehlweni, esikhunjeni, isipheshana sokuphefumula kanye nohlelo lokugaya. Ngesikhathi sokusebenza, ukunakekelwa kufanele kuthathwe ukugwema ukuxhumana nesikhumba namehlo, futhi kuqinisekiswe ukuthi ukuhlinzwa kwenziwa kahle ngaphansi - izimo zomoya.
Kuwuketshezi olungenamibala futhi olusobala olunephunga elingathandeki. Isimo esilinganiselwe ngu-0.9668 (20/3 ℃), iphuzu lokuncibilika lingu -75 ℃, futhi iphuzu elibilayo lingu-198 ℃. Kuyancibilika ku-organic solvents enjenge-ether. Kubola nge-butterric acid lapho kuhlangana namanzi. Iphendula ngotshwala ukwakha ama-esters. Kuwuketshezi olungenamibala, olusobala futhi oluvuthayo. Kuyancibilika emanzini futhi kububula ama-buthric acid, futhi kuyancibilika ku-ether.
Ukupakisha nokuthumela
195 kg / isigubhu noma njengezidingo zamakhasimende.
Kungokwezimpahla ezijwayelekile futhi kungahambisa ngo-Ocean nomoya
Gcina futhi ugcine
I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.
