Hoʻolauna
3,4-Dimethylbenzophenone, i ʻike ʻia he ketocarbonate a i ʻole Benzoin. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Keʻano: 3,4-Dimethylbenzophenone he paʻa keʻokeʻo keʻokeʻo.
-Solubility: Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, a he kiʻekiʻe ka solubility i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide.
-Ka helu hoʻoheheʻe: ʻO ka helu hoʻoheheʻe o 3,4-dimethylbenzophenone ma kahi o 132-134 degere Celsius.
-Kemimi waiwai: He electrophilic reagent hiki ke komo i loko o nā ʻano like ʻole e like me ka hoʻokumu ʻana o ka hydrogen bond, ka hopena oxidation-reduction ma waena o ketone carbon a me methyl.
E hoʻohana:
- Hoʻohana nui ʻia ka 3,4-Dimethyl benzophenone ma ke ʻano he reagent no nā hopena synthesis organik.
-Hiki ke hoʻohana ʻia ma ke ʻano he electrophilic reagent e komo i nā hopena hoʻohui electrophilic, ketone carbonate formation a me nā hopena ʻē aʻe.
-Hiki ke hoʻohana ʻia e like me ka photosensitizer no ka lithography, ka mālama māmā a me nā māla ʻē aʻe.
Kaʻina hoʻomākaukau:
ʻO kahi ala no ka hoʻomākaukau ʻana o -3,4-dimethyl benzophenone ka hopena synthesis o barone. Penei nā ʻanuʻu o ka pane ʻana: ʻO ka mua, ua hana ʻia ka styrene me ka bromine keu ma lalo o ke kukui a i ʻole ke kukui ultraviolet e hana i ka β-bromostyrene. Hoʻopili ʻia ka β-bromostyrene me kahi hydroxide (eg, NaOH) e hana i ka 3,4-dimethylbenzophenone.
- ʻO kahi ʻano hoʻomākaukau ʻē aʻe e hana i ka acetophenone a me ka sodium bromide ma lalo o nā kūlana alkaline e hana ai i ka 3,4-dimethyl benzophenone.
ʻIke palekana:
- ʻO 3,4-Dimethylbenzophenone ka mea ʻona.
-E hōʻalo i ka ʻili a me ka inhalation ke hoʻohana.
-Ruyi pili waho i ka ʻili, pono e holoi koke me ka wai nui.
-Inā inhaled, e neʻe koke i kahi maikaʻi ventilated.
- Manaʻo ʻia e komo i nā mīkina lima pale kūpono a me nā mea hanu i ka wā o ka hana.
-I ka hoʻohana ʻana a mālama ʻana, e ʻoluʻolu e hahai i nā kaʻina hana palekana a waiho i waho o ka hiki ʻana o nā keiki.
