Kupu Whakataki

āhuatanga matū

He wai muramura kore tae me te haunga o te aldehyde. He iti te wairewa ki te wai. Miscible ki te waihano, ether, ethyl acetate, acetone, toluene, etahi atu momo whakarewa pararopi me nga hinu.

Whakamahi

Ka whakamahia i roto i te whakahiato waro me te rauemi mata mo te hanga mea kakara

Whakamahi

Ko te GB 2760-96 e whakaatu ana i nga mea kakara ka taea te whakamahi. Ka whakamahia te nuinga ki te whakarite panana, karamere me etahi atu mea kakara.

Whakamahi

he takawaenga nui te butyraldehyde. Ka taea te hanga n-butanol ma te hauwai o te n-butanal; Ka taea te whakaputa i te 2-ethylhexanol na roto i te whakamaroketanga condensation, katahi ka hauwai, a, ko te n-butanol me te 2-ethylhexanol nga rauemi mata matua o nga kaiparapara. Ko te waikawa n-butyric ka taea te whakaputa i te waiora o te waikawa n-butyric; Ko te trimethylolpropane ka taea te whakaputa ma te whakakoi me te formaldehyde, he mea whakahiato mo te whakahiato o te kapia alkyd me te rauemi mata mo te hinu whakamaroke hau; te whakamahana me te phenol hei whakaputa i te kapia wairewa-hinu; ka taea e te condensation me te Urea te whakaputa kapia wairewa-wairewa; Ko nga hua kua whakapoapoa ki te waipiro polyvinyl, butylamine, thiourea, diphenylguanidine, methyl carbamate ranei he rauemi mata, a, ka whakamahia te whakamahana me nga momo waipiro hei whakarewa mo te celluloid, te kapia, te rapa me nga hua rongoa; whakamahia te ahumahi ho'oraa ki te hanga "Mianerton", "pyrimethamine", me amylamide.

Whakamahi

Kāpia rapa, whakatere rapa, hākawa kapia waihanga, hanga waikawa butyric, aha atu. Ko tana otinga hexane he reagent hei whakatau i te ozone. Ka whakamahia hei whakarewa mo nga lipids, ka whakamahia ano ki te whakarite i nga mea kakara me nga mea kakara me te tiaki.

Tikanga whakaputa

I tenei wa, ko nga tikanga hanga o te butyraldehyde e whai ake nei: 1. propylene carbonyl synthesis method propylene me te synthesis hau e kawe ana i te tauhohenga whakahiato waro i te aroaro o te Co, Rh ranei hei whakaputa i te n-butyraldehyde me te isobutyraldehyde. Na nga rereke rereke me nga tikanga tukanga e whakamahia ana, ka taea te wehewehe ki te konupora waro-nui-a-te-nui me te waro-a-te-te-te-waowa hei whakakorikori me te iti-pēhanga carbonyl synthesis me te rhodium carbonyl phosphine matatini hei whakakorikori. Ko te tikanga pehanga teitei he nui te pehanga tauhohenga me te maha o nga hua-hua, na reira ka piki ake te utu whakaputa. Ko te tikanga whakahiato carbonyl iti-pēhanga he iti te pehanga tauhohenga, te tauwehenga inehe pai o te 8-10: 1, he iti ake nga hua, te tere o te hurihanga, te iti rawa o nga rauemi mata, te iti o te kaha, te taputapu ngawari, te tukanga poto, e whakaatu ana i nga painga ohaoha pai me whanaketanga tere. 2. Tikanga whakapoapoa acetaldehyde. 3. Ko te tikanga whakangao waiora o te Butanol te whakamahi i te hiriwa hei whakakorikori, a ka oxidized te butanol e te hau i roto i te hikoi kotahi, katahi ka whakapoapoa, ka wehea, ka whakatikahia te butanol kia whiwhi ai i te hua kua oti.

Tikanga whakaputa

Ka whiwhihia ma te whakamaroke maroke o te konupūmā butyrate me te konupūmā hōputu.

Ka whiwhi te kohu na roto i te whakakorenga o te whakakorikori.
