Hoʻolauna
ʻO 4-Methylphenylacetone, ʻike ʻia hoʻi ʻo 4-methylphenylacetone, he mea hoʻohuihui.
Eia kekahi mau waiwai nui e pili ana i ka 4-methylpropionone:
1. Nānā: wai kala ʻole a i ʻole aniani keʻokeʻo.
2. Māmā: 0.993g/mLat 25°C(māmā)
5. Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me benzene.
6. Paʻa ka mālama ʻana: Pono e mālama ʻia mai nā lapalapa a me nā oxidants, a mālama ʻia i kahi maloʻo, ʻoluʻolu a me ka makani.
4-Methylpropiophenone kekahi mau hoʻohana ma kekahi mau wahi, me:
2. Hoʻohana i ka noiʻi: Ma ka synthesis organik, hiki ke hoʻohana ʻia ma ke ʻano he precursor o nā ketones a i ʻole nā ʻawaʻawa no ka synthesis o nā mea hoʻohui ʻē aʻe.
ʻO nā ala maʻamau no ka hoʻomākaukau ʻana i ka 4-methylpropiophenone he:
1. Ka pane ʻo Marthet: Hoʻopili ʻia ka Styrene a me ke kalapona kalapona i loko o kahi reactor sweep apo mau no ka loaʻa ʻana o 4-methylacetophenone, a laila hoʻomākaukau ʻia ka 4-methylacetophenone e ka oxidation a me ka hōʻemi.
2. ʻO ka pane ʻana o Vilsmeier–Haack: Hoʻopili ʻia ka Phenylethanol me ka waikawa nitric a me ka phosphine ma lalo o nā kūlana hopena o ka alkylation o nā alkylloids e loaʻa ai ka 4-methylphenylacetone.
1. E pale i ka pili ana me ka ili, ka maka a me ka mucous membranes.
3. E hō'ole i ka ho'ohu 'ana i ka mahu a i 'ole ka noe, a e ho'okomo i nā mīkina lima pale kūpono, nā maka maka makamae, a me nā lole pale i ka wā e ho'ohana ai.
5. I ka mālama ʻana a me ka lawelawe ʻana, e pale i ka hoʻopili ʻana me nā mea hiki ke puhi ʻia a waiho i loko o kahi pahu paʻa i ka ea, ma kahi mamao mai nā kumu wela a me nā lapalapa ahi.
