Folasaga	benzoyl chloride (CAS98-88-4) ua taʻua foi o le benzoyl chloride, benzoyl chloride, e aofia i se ituaiga o chloride acid. O le vai mama e leai se lanu manino e mu, fa'aalia i le asu o le ea. O oloa faʻapisinisi ma samasama samasama, faʻatasi ai ma se manogi malosi faʻafefe. O le ausa i luga o le mata mucosa, paʻu ma le manava o loʻo i ai se aafiaga malosi faʻaosofia, e ala i le faʻaosofia o le mata mucosa ma loimata. O le Benzoyl chloride o se mea taua tele mo le saunia o vali, mea manogi, organic peroxides, vailaʻau ma resini. Ua faʻaaogaina foʻi i ata pue ma le gaosiga o tannins, ma ua faʻaaogaina e fai ma kesi faʻamalosi i taua faʻa-chemika. Ata 1 o le fa'asologa fa'atulagaina o le benzoyl chloride
auala sauniuni	i totonu o le falesuesue, e mafai ona maua le benzoyl chloride e ala i le distilling benzoic acid ma phosphorus pentachloride i lalo o tulaga anhydrous. E mafai ona maua le auala sauniuni fale gaosi oloa e ala i le faʻaaogaina o le thionyl chloride ma le benzaldehyde chloride.

auala gaosiga	1. Toluene auala mea mata toluene ma chlorine i le malamalama i lalo o le tulaga o le tali, filifili filifili chlorination e maua ai le α-trichlorotoluene, le mulimuli i le acidic medium hydrolysis e maua ai le benzoyl chloride, ma le tatalaina o le hydrogen chloride kasa (gaosiga o vai absorption. o le kasa HCl). 2. Benzoic acid ma tali phosgene. O le vailaʻau benzoic e tuʻuina i totonu o se fagu photochemical, faʻamafanafana ma faʻafefete, ma faʻafeiloaʻi le phosgene i le 140-150 ℃. O le kasa si'usi'u tali o lo'o i ai le hydrogen chloride ma le phosgene unreacted, lea e togafitia i le alkali ma fa'afefe, o le vevela i le faaiuga o le tali na -2-3 ° c, ma o le oloa na fa'amama i lalo o le fa'aitiitia o le mamafa pe a uma le gaioiga o le kesi. O oloa fa'apisinisi o vai samasama manino. Mama ≥ 98%. Ole aofa'i ole fa'aaogāina o mea mata'utia: acid benzoic 920kg/t, phosgene 1100kg/t, dimethylformamide 3kg/t, alkali vai (30%)900kg/t. Ua fa'aaogaina lautele i le alamanuia o le benzoic acid ma le benzylidene chloride sauniuniga tali. E mafai foi ona maua le Benzoyl chloride e ala ile chlorination tuusao ole benzaldehyde. E tele auala sauniuni. (1) O le benzoic acid e faʻamafanafanaina ma faʻafefeteina e ala i le phosgene, ma faʻafeiloaʻi le phosgene i le 140 ~ 150 ℃, ma o se aofaʻi o phosgene e faʻafeiloaʻi e oʻo atu i le pito iʻuga. O le phosgene o loʻo faʻauluina e le nitrogen, ma o le siʻusiʻu kesi e faʻafefe ma faʻaumatia, o le mea mulimuli na maua e ala i le faʻamama i lalo o le faʻaitiitia o le mamafa. (2) phosphorus trichloride auala benzoic acid solo i toluene ma isi solvents, Phosphorus trichloride faaopoopo dropwise, ma o le tali na faia mo le tele o itula ina ua uma ona pa'ū, ua faamamaina le toluene, ona faamamaina ai lea o le oloa maeʻa. (3) auala trichloromethylbenzene e toluene filifili filifili chlorination, ona hydrolysis oloa.
