Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso

Isingeniso

I-Trans-cinnamic acid iyinhlanganisela yezinto eziphilayo. Itholakala ngendlela yamakristalu amhlophe noma ama-crystalline powders.

 

I-Trans-cinnamic acid iqinile ezingeni lokushisa legumbi futhi ingancibilika otshwaleni, kuma-ether nezincibilikisi ze-asidi, futhi inyibilika kancane emanzini. Inephunga elimnandi elikhethekile.

 

I-Trans-cinnamic acid inezinhlobonhlobo zokusetshenziswa.

 

Indlela yokulungiselela i-trans-cinnamic acid ingatholakala ngokusabela kwe-benzaldehyde ne-acrylic acid. Izindlela zokulungiselela ezivame ukusetshenziswa zifaka ukusabela kwe-oxidation, ukusabela kwe-acid-catalyzed kanye ne-alkaline catalytic reaction.

Isibonelo, gwema ukuthintana ngqo nesikhumba namehlo ukuze ugweme ukucasuka nokuvuvukala. Lapho kusebenza, kufanele kusetshenziswe izinto zokuzivikela ezifanele, njengamagilavu ​​aselabhorethri, izibuko zokuzivikela, njll. I-Trans-cinnamic acid kufanele igcinwe kahle ukuze kugwenywe ukuthintana nemithombo yokuthungela kanye nama-oxidants ukuvimbela izingozi zomlilo nokuqhuma. Ngesikhathi sokusebenzisa, sebenzisa ngokuhambisana nenqubo efanele kanye nemininingwane yokusebenza ukuze uqinisekise ukuphepha.
