Kupu Whakataki
3,4-Dimethylbenzophenone, e mohiotia ana ko te ketocarbonate ko Benzoin ranei. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te whakarite me nga korero haumaru:
Taiao:
-Whakaahua: Ko te 3,4-Dimethylbenzophenone he toka tioata ma.
-Solubility: He tata kore e rewa ki te wai, a he nui te whakarewatanga i roto i nga whakarewa waro penei i te ethanol me te dimethylformamide.
-Ko te tohu whakarewa: Ko te rewa o te 3,4-dimethylbenzophenone e pa ana ki te 132-134 nga nekehanga Celsius.
-Nga mea matū: He tauhohenga hiko ka taea te uru atu ki nga momo tauhohenga penei i te hanganga here hauwai, te tauhohenga whakangao-whakaheke i waenga i te waro ketone me te methyl.
Whakamahia:
- Ko te 3,4-Dimethyl benzophenone te nuinga ka whakamahia hei reagent mo nga tauhohenga whakahiato waro.
-Ka taea te whakamahi hei reagent electrophilic ki te uru atu ki nga tauhohenga taapiri electrophilic, te hanga ketone carbonate me etahi atu tauhohenga.
-Ka taea hoki te whakamahi hei whakaahua whakaahua mo te lithography, te rongoa marama me etahi atu mara.
Tikanga Whakaritenga:
Ko tetahi tikanga mo te whakarite -3,4-dimethyl benzophenone ko te hohenga synthesis o te barone. Ko nga hikoinga o te tauhohenga e whai ake nei: Tuatahi, ka tauhohehia te styrene ki te nui o te bromine i raro i te marama, i te rama ultraviolet ranei hei hanga β-bromostyrene. Ka tauhohehia te β-bromostyrene ki te waihā (hei tauira, NaOH) hei hanga 3,4-dimethylbenzophenone.
-Ko tetahi atu tikanga whakarite ko te whakahoki i te acetophenone me te konutai bromide i raro i nga tikanga kawakore ki te whakaputa 3,4-dimethyl benzophenone.
Mōhiohio Haumaru:
- Ko te 3,4-Dimethylbenzophenone he iti ake te paitini.
-Kaore i te pa ki te kiri me te inhalation ina whakamahi.
-Ruyi whakapā waho ki te kiri, me horoi tonu ki te nui o te wai.
-Mena ka ngohia, me neke tonu ki te waahi whai hau.
-E taunaki ana kia mau nga karapu tiaki tika me nga taputapu manawa i te wa e mahi ana.
-I te wa e whakamahi ana me te penapena, me whai i nga tikanga whakahaere haumaru ka waiho kia kore e taea e nga tamariki.
