Mawu Oyamba
Tosylisocyanate, yemwenso amadziwika kuti Tosylisocyanate. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha p-toluenesulfonylisocyanate:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena opepuka achikasu.
- Kusungunuka: Kusungunuka muzosungunulira za organic, monga ethanol, dimethylformamide, ndi zina.
- Kukhazikika: Kukhazikika, koma kukhudzana ndi madzi ndi alkalis amphamvu kuyenera kupewedwa.
Gwiritsani ntchito:
Tosyl isocyanate imagwiritsidwa ntchito makamaka ngati reagent kapena poyambira poyambira ma organic synthesis reaction. Tosyl isocyanate itha kugwiritsidwanso ntchito ngati chothandizira komanso gulu loteteza mu chemistry yopanga.
Njira:
Njira yokonzekera toluenesulfonyl isocyanate nthawi zambiri imapezeka pochita benzoate sulfonyl chloride ndi isocyanate. Masitepe enieni akuphatikizapo zomwe sulfonyl chloride benzoate ndi isocyanate pamaso pa maziko, m'chipinda kapena kutentha kochepa. The mankhwala anachita yotengedwa ndi kuyeretsedwa ndi njira monga zosungunulira m'zigawo ndi crystallization.
Zambiri Zachitetezo:
- Kukhudzana ndi khungu ndi maso kuyenera kupewedwa panthawi ya opaleshoni kuti asapse kapena kuvulala.
- Malo ogwirira ntchito akuyenera kukhala ndi mpweya wabwino komanso kupewa kutulutsa mpweya wake.
- Pakusungirako ndi kunyamula, kukhudzana ndi chinyezi ndi alkalis amphamvu kuyenera kupewedwa kuti zisawonongeke.
- Tsatirani njira zoyenera zotetezera ndikuvala zida zoyenera zodzitetezera mukamagwiritsa ntchito tosyl isocyanate.
