3-Fluorobenzoyl chloride (CAS# 1711-07-5) chiyambi
M-fluorobenzoyl chloride (yomwe imadziwikanso kuti 2-fluorobenzoyl chloride) ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera mwatsatanetsatane za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha mankhwalawa.
Ubwino:
M-fluorobenzoyl chloride ndi madzi achikasu otumbululuka opanda mtundu omwe amakhala ndi zokometsera komanso fungo loyipa kwambiri pa kutentha kokwanira. Sasungunuke m'madzi, koma imatha kukhala yosakanikirana ndi zosungunulira organic monga ethers, ketones, alcohols, etc.
Ntchito: Itha kugwiritsidwa ntchito popanga ma ketones onunkhira (mwachitsanzo, foryl chloride) ndi ma amides (mwachitsanzo, forylchloramine). Itha kugwiritsidwanso ntchito ngati chinthu chapakati chofunikira pamankhwala ophera tizilombo ndi utoto.
Njira:
Njira yokonzekera ya m-fluorobenzoyl chloride nthawi zambiri imakhala ndi m-fluorobenzoic acid ndi anhydrous thionyl chloride. Zomwe zimachitikira ziyenera kuchitika mumlengalenga komanso kutentha kochepa. Pamapeto pa zomwe zimachitika, chomalizacho chikhoza kupezedwa ndi mankhwala ndi madzi ndi yankho la acidic.
Zambiri Zachitetezo:
M-fluorobenzoyl chloride ndi mankhwala omwe amatha kuyambitsa kuyabwa komanso kuyaka mukakhudza khungu ndi maso. Zida zodzitetezera zoyenerera monga magolovesi, magalasi, ndi zovala zodzitchinjiriza ziyenera kuvalidwa pogwira ntchito. Pawiri ayenera kusungidwa bwino, kupewa kukhudzana ndi zinthu monga okosijeni ndi alkalis amphamvu, ndipo kupewa kuyatsa ndi kutentha kwambiri.
