| Hordhac | benzoyl chloride (CAS98-88-4) sidoo kale loo yaqaano benzoyl chloride, benzoyl chloride, oo ka tirsan nooc ka mid ah chloride acid. Dareere guban kara oo aan midab lahayn oo saafi ah, gaadhista qiiq hawo. Alaabooyinka warshadaha leh huruud khafiif ah, oo leh ur xanaaq badan. Uumiga ku yaal xuubka isha, maqaarka iyo mareenka neef-mareenka wuxuu leeyahay saameyn xoog leh oo kicinaysa, iyadoo kicinaysa xuubka isha iyo jeexjeexyada. Benzoyl chloride waa dhexdhexaad muhiim ah oo loogu talagalay diyaarinta dheeha, udgoonka, peroxides organic, daawooyinka iyo resins. Waxa kale oo loo isticmaali jiray sawir-qaadista iyo soo saarista tannins-ka macmalka ah, waxaana loo adeegsaday gaasta kiciya ee dagaalka kiimikada. Jaantuska 1 waa qaacidada qaab dhismeedka ee benzoyl chloride |
| habka diyaarinta | Shaybaarka dhexdiisa, chloride benzoyl waxaa lagu heli karaa iyadoo la nadiifiyo benzoic acid iyo fosfooraska pentachloride iyadoo lagu jiro xaalado aan biyo lahayn. Habka diyaarinta warshadaha waxaa lagu heli karaa iyadoo la isticmaalayo thionyl chloride iyo chloride benzaldehyde. |
| qaybta khatarta | Qaybta khatarta ah ee chloride benzoyl: 8 |
| Isticmaal | chloride benzoyl waa dhexdhexaad ah oxazinone herbicide, sidoo kale waa dhexdhexaad ah benzenecapid cayayaanka, hydrazine inhibitor. chloride benzoyl waxaa loo isticmaalaa sida walxo cayriin ah oo loogu talagalay isku-darka organic, dheeha iyo daawooyinka, iyo bilawga, dibenzoyl peroxide, tert-butyl peroxide, cayayaanka cayayaanka, iwm. , Karphos) dhexdhexaadiye. Sidoo kale waa benzoylation muhiim ah iyo reagent benzylation. Inta badan chloride benzoyl waxaa loo isticmaalaa in lagu soo saaro benzoyl peroxide, oo ay ku xigto wax soo saarka benzophenone, benzyl benzoate, benzyl cellulose iyo benzamide iyo walxo kale oo kiimiko ah oo muhiim ah, benzoyl peroxide ee bilawga polymerization ee monomer caag ah, polyester, epoxy, kicinta resin acrylic. wax soo saarka, is-xinjirowga walxaha fiber galaas, wakiilka crosslinking ee fluororubber silicone, sifaynta saliidda, bur bleaching, fiber decolorization, iwm. Intaa waxaa dheer, benzoic acid waxaa lagu falcelin karaa benzoyl chloride si loo soo saaro benzoic anhydride. Isticmaalka ugu weyn ee benzoic anhydride waa sida wakiilka acylating, sida qayb ka mid ah wakiilka bleaching iyo qulqulka, iyo sidoo kale diyaarinta benzoyl peroxide. loo isticmaalo sida reagents gorfaynta, sidoo kale loo isticmaalo dhir udgoon, synthesis organic |
| habka wax soo saarka | 1. Habka Toluene ee alaabta ceeriin ee toluene iyo chlorine ee iftiinka hoos yimaada xaaladda falcelinta, chlorination silsilad dhinaca si ay u soo saaraan α-trichlorotoluene, dambe ee hydrolysis dhexdhexaad ah acidic si ay u abuuraan chloride benzoyl, iyo sii daayo of hydrogen chloride gaaska (soosaarka nuugista biyaha). gaaska HCl). 2. Benzoic acid iyo falcelinta fosgene-ka. Aashitada benzoic waxaa lagu shubaa dheri kiimikaad ah, kulayl iyo dhalaali, iyo fosgene-ka waxaa lagu soo bandhigay 140-150 ℃. Gaaska dabada falcelinta waxaa ku jira hydrogen chloride iyo fosgene aan falcelin lahayn, kaas oo lagu daaweeyay alkali oo hawada laga saaray, heerkulka dhamaadka falcelinta wuxuu ahaa -2-3 °c, iyo badeecada waxaa lagu shubay cadaadis hoos u dhacay ka dib hawlgalka saarista gaaska. Alaabooyinka warshaduhu waa dareere hufan oo hurdi ah. daahirnimo ≥ 98%. Kootada isticmaalka alaabta ceeriin: benzoic acid 920kg/t, fosgene 1100kg/t, dimethylformamide 3kg/t, alkali dareere (30%) 900kg/t. Hadda si weyn loogu isticmaalo warshadaha benzoic acid iyo diyaarinta falcelinta chloride benzylidene. Benzoyl chloride sidoo kale waxaa lagu heli karaa koloriinta tooska ah ee benzaldehyde. Waxaa jira dhowr habab oo diyaarin ah. (1) Aashitada benzoic waa la kululeeyaa oo lagu dhalaaliya habka fosgene-ka, fosgene-ka waxaa lagu soo bandhigaa 140 ~ 150 ℃, iyo qadar go'an oo fosgene ah ayaa la soo bandhigay si loo gaaro meesha ugu dambeysa. Fosgene-ka waxaa dhaqaajiya nitrogen, iyo gaaska dabada waa la nuugo oo la burburiyaa, badeecada ugu dambeysa waxaa lagu helay hoos u dhigista cadaadiska hoos u dhaca. (2) Habka fosfooraska trichloride benzoic acid ayaa lagu milmay toluene iyo dareerayaasha kale, fosfooraska trichloride waxaa lagu daray hoos u dhac, falcelinta ayaa la sameeyay dhowr saacadood ka dib markii la soo tuuray, toluene waa la nadiifiyaa, ka dibna badeecada dhammaatay waa la nadiifiyaa. (3) Habka trichloromethylbenzene si toluene silsiladda chlorination, ka dibna alaabta hydrolysis. |
