Hordhac
3,4-Dimethylbenzophenone, oo sidoo kale loo yaqaan ketocarbonate ama Benzoin. Kuwa soo socda waa sharaxaadda dabeecadeeda, isticmaalkeeda, diyaarinteeda iyo macluumaadka badbaadada:
Dabeecadda:
-Muuqaalka: 3,4-Dimethylbenzophenone waa crystalline cad oo adag.
-Solubility: Waxay ku dhowdahay inaan lagu milmi karin biyaha, waxayna leedahay milmi sare oo dareerayaasha organic sida ethanol iyo dimethylformamide.
-Dhibka dhalaalka: Barta dhalaalka ee 3,4-dimethylbenzophenone waa qiyaastii 132-134 darajo Celsius.
Guryaha kiimikaad: Waa reagent electrophilic kaas oo ka qaybqaadan kara falcelino kala duwan sida samaynta curaarta hydrogen, falcelinta dhimista oksaydhka ee u dhexeeya ketone carbon iyo methyl.
Isticmaal:
-3,4-Dimethyl benzophenone waxaa inta badan loo isticmaalaa sidii reagent falcelinta synthesis organic.
-Waxa loo isticmaali karaa sida reagent electrophilic si ay uga qaybqaataan falcelinta isku darka korantada, samaynta carbonate ketone iyo falcelinta kale.
-Waxa kale oo loo isticmaali karaa sawir-qaade ahaan xagga qoraalka, daawaynta iftiinka iyo qaybaha kale.
Habka Diyaarinta:
Mid ka mid ah habka loogu talagalay diyaarinta -3,4-dimethyl benzophenone waa falcelinta falcelinta barone. Tallaabooyinka falcelintu waa sida soo socota: Marka hore, styrene waxaa lagu falceliyaa bromine-ka xad-dhaafka ah ee iftiinka ama iftiinka ultraviolet si loo sameeyo β-bromostyrene. β-bromostyrene ayaa markaa lagu falceliyaa hydroxide (tusaale, NaOH) si loo sameeyo 3,4-dimethylbenzophenone.
-Qaabka kale ee diyaarinta waa in laga falceliyo acetophenone iyo sodium bromide hoos yimaada xaaladaha alkaline si loo abuuro 3,4-dimethyl benzophenone.
Macluumaadka Badbaadada:
-3,4-Dimethylbenzophenone way ka yar tahay sunta.
-Ka fogow taabashada maqaarka iyo neefsashada markaad isticmaalayso.
-Taabashka dibadda ee Ruyi ee maqaarka, waa in isla markiiba ku luqluqdo biyo badan.
-Haddii la nuugo, isla markiiba u dhaqaaq meel hawo fiican leh.
-Waxaa lagu talinayaa in la xidho galoofyada ilaalinta habboon iyo qalabka neefsashada inta lagu jiro hawlgalka.
-Markaad isticmaalayso oo aad kaydinayso, fadlan raac nidaamka qalliinka ee badbaadsan oo dhig meel aan carruurtu gaadhi karin.
