Lambarka CAS: 100-44-7

Benzyl chloride, oo sidoo kale loo yaqaan benzyl chloride iyo toluene chloride, waa dareere aan midab lahayn oo leh ur xooggan oo udgoon. Waxaa lagu milmi karaa dareere dabiici ah sida chloroform, ethanol, iyo ether. Ma milmi karo biyaha laakiin wuu uumi bixi karaa iyadoo uumi biyo ah. Uumigeedu wuxuu dhibaa xuubka xuubka indhaha waana wakiil xoog leh oo kiciya ilmada. Isla mar ahaantaana, benzyl chloride sidoo kale waa dhexdhexaad ka mid ah isku-darka dabiiciga ah waxaana si weyn loogu isticmaalaa isku-darka midabaynta, sunta cayayaanka, udgoonka macmal ah, saabuunta, balaastikada, iyo daawooyinka.

Waxaa jira habab badan oo isku-darka ah oo loogu talagalay benzyl chloride, oo ay ugu horreeyaan habka koloriinaynta benzyl alcohol, habka chloromethyl, habka koloriinaynta toluene catalytic, iwm. Kuwaas waxaa ka mid ah habka koloriinaynta benzyl alcohol waxaa lagu helaa falcelinta benzyl alcohol iyo hydrochloric acid. Waa habka isku-darka ugu horreeya ee benzyl chloride. Habka chloromethyl sidoo kale waa hab warshadeed oo hore. Alaabteeda ceeriin waa benzene iyo benzaldehyde (ama trimerformaldehyde). Koloriin zinc aan biyo lahayn ayaa loo isticmaalaa sidii kaalshiyam. Koloriinaynta catalytic ee toluene hadda waa habka wax soo saarka warshadaha ee ugu badan ee benzyl chloride, koloriinaynta catalytic ee toluene-na waxaa loo qaybin karaa koloriinaynta photocatalytic iyo koloriinaynta catalytic heerkulka hooseeya. Si kastaba ha ahaatee, habka koloriinaynta photocatalytic waxay u baahan tahay rakibidda ilo iftiin ah oo gudaha qalabka ah, kaas oo leh astaamo ay adag tahay in la xakameeyo falcelinta, falcelin dhinacyo badan leh, iyo kharash sare. Habka koloriin-ka kicinta heerkulka hooseeya wuxuu adeegsadaa mid ama in ka badan oo dibenzoyl peroxide ah, azobisisobutyronitrile, iyo acetamide oo ah kiciye si uu uga falceliyo toluene iyo koloriin heerkulka hooseeya, isagoo isticmaalaya heerkul hooseeya iyo koloriin Xakamee heerka falcelinta si loo hagaajiyo heerka beddelka iyo xulashada, laakiin xaalado gaar ah ayaa weli u baahan in la sahamiyo.

Heerkulka kala-soocidda ee benzyl chloride guud ahaan waxaa lagu sameeyaa 100°C waana in uusan ka badnaan 170°C. Tani waa sababta oo ah benzyl chloride waa walax xasaasiyad ku leh kulaylka. Haddii heerkulku aad u sarreeyo, falgal is-polymerization ah ayaa dhici doona. Haddii falgalku aad u xoog badan yahay, waxaa jiri doona khatar qarax. Sidaa darteed, kala-soocidda benzyl chloride cayriin ah ayaa loo baahan yahay in lagu sameeyo cadaadis taban. Isla mar ahaantaana, waxaa lagama maarmaan ah in la xakameeyo waxa ku jira ion-ka birta ee ku jira xalka koloriinaynta, sababtoo ah benzyl chloride wuxuu mari doonaa falgal Krafts-Kreider iyadoo ay joogaan ion-yada birta iyo heerkul sare, waxaana la soo saari doonaa walax resinous ah, taasoo keeni doonta in dareeruhu noqdo mid mugdi ah oo la sii daayo xaddi badan oo gaas hydrogen chloride ah.

Codsiyada

Benzyl chloride waa dareere muhiim ah oo dabiici ah. Badeecada warshadeed waa dareere aan midab lahayn ama huruud khafiif ah oo hufan oo leh ur daran iyo daxal xooggan. Waxaa lagu milmi karaa dareerayaasha dabiiciga ah sida ether, chloroform, iyo chlorobenzene. Benzyl chloride si weyn ayaa loogu isticmaalaa warshadaha. Waxaa inta badan loo isticmaalaa beeraha sunta cayayaanka, daawooyinka, dhir udgoonka, kaaliyaha rinjiga, iyo kaaliyaha macmal ah. Waxaa loo isticmaalaa in lagu sameeyo laguna soo saaro benzaldehyde, butyl benzyl phthalate, aniline, phoxim, iyo benzyl chloride. Penicillin, benzyl alcohol, phenylacetonitrile, phenylacetic acid iyo alaabooyin kale.

Benzyl chloride waxay ka tirsan tahay fasalka benzyl halide ee isku-dhafka cuncunka leh. Marka laga hadlayo sunta cayayaanka, si toos ah uma soo saari karto oo keliya fungicides-ka organophosphorus, shabakada bariiska ee qarxa iyo shabakadda bariiska ee iso, laakiin sidoo kale waxaa loo isticmaali karaa walxo cayriin oo muhiim u ah dhexdhexaadinta kale ee badan, sida isku-darka phenylacetonitrile iyo benzene. Formyl chloride, m-phenoxybenzaldehyde, iwm. Intaa waxaa dheer, benzyl chloride waxaa si weyn loogu isticmaalaa daawada, xawaashka, kaaliyaha rinjiga, resins-ka synthetic-ga, iwm. Waa dhexdhexaad muhiim ah oo wax soo saarka kiimikada iyo dawooyinka ah. Markaa dareeraha qashinka ama qashinka ay soo saaraan shirkadaha inta lagu jiro habka wax soo saarka waxaa si lama huraan ah uga kooban xaddi badan oo dhexdhexaad ah oo benzyl chloride ah.

Benzyl chloride lafteedu waa mid keenta jeexjeex, aad u sun badan, keenta kansar, iyo deegaan ahaan waa mid aan dhib lahayn. Maadaama benzyl chloride lafteeda si weyn loo isticmaalo loona isticmaalo xaddi badan, benzyl chloride ayaa daadata inta lagu jiro rarista ama waxaa soo saara soosaarayaal kala duwan. Dareeraha qashinka ah ee ka kooban benzyl chloride ee shirkaddu keento inta lagu jiro habka wax soo saarka ama qashinka ayaa si toos ah loo tuuraa, ama daadashada ayaa dhacda inta lagu jiro habka wax soo saarka, taasoo si toos ah u sababi doonta benzyl chloride inay gasho ciidda oo ugu dambeyntii wasakhayso ciidda.
