Kupu Whakataki

Ko te 4-Methylphenylacetone, e mohiotia ana ko 4-methylphenylacetone, he puhui waro.

Anei etahi taonga nui mo te 4-methylpropionone:

1. Te ahua: te wai kore tae, te karaihe ma ranei.

2. Kiato: 0.993g/mLat 25°C(marama)

5. Wairewa: Ka whakarewahia i roto i nga whakarewa waro penei i te waihano, te etera me te benzene.

6. Rokiroki pūmautanga: Me pupuri atu i te mura tuwhera me te hāora, ka rongoa i roto i te wahi maroke, hauhautanga me te hā.

4-Methylpropiophenone etahi whakamahinga i etahi waahi, tae atu ki:

2. Whakamahi Rangahau: I roto i te whakahiato waro, ka taea te whakamahi hei tohu o te ketones, te waipiro ranei mo te whakahiato o etahi atu puhui waro.

Ko nga tikanga noa mo te whakarite i te 4-methylpropiophenone ko:

1. Tauhohenga Marthet: Ka tauhohehia te Styrene me te waro hauhaa i roto i te reactor sweep mowhiti tonu kia whiwhi 4-methylacetophenone, katahi ka rite te 4-methylacetophenone ma te waiora me te whakaheke.

2. Tauhohenga Vilsmeier–Haack: Ka tauhohehia te Phenylethanol ki te waikawa nitric me te phosphine i raro i nga tikanga tauhohenga o te alkylation o alkylloids ki te whiwhi 4-methylphenylacetone.

1. Kaua e pa atu ki te kiri, ki nga kanohi me nga kiri mucous.

3. A ape i te tango i te kohu, i te kohu ranei, ka mau i nga karapu whakamarumaru e tika ana, nga karaehe, me nga kakahu whakamarumaru ina whakamahi.

5. I te wa e rongoa ana me te whakahaere, karohia te pa atu ki nga matū muramura me te rongoa ki roto i te ipu hau, kia matara atu i nga puna wera me nga mura ahi.
