Te takai o roto

I te nuinga o te wa ka whakamahia ki te kohi paura.A ka taea e ratou te aukati i te ra me te wai kia kino.

tarapi waho

Ka taea e te kaata pakeke te tiaki i o hua mai i te pakaru me te makuku.

Nga tono

He mea hanga mai i te tauhohenga esterization o te waikawa pararopi, te waikawa waro, te waipiro ranei.Ko te waipiro, te phenol, te anhydride waikawa ranei, te waipiro me te ethylene, te waikawa waikawa kore utu me nga hua hauota ngako ka taea hoki te whakaputa ester.Ko te hauwai kei runga i te alpha-carbon i roto i nga ngota ngota ester ka ngaro te waipiro ngota me tetahi atu ester ngota i raro i nga tikanga kawakore ki te whakaputa i te β-keto ester, e kiia nei ko te ester contraction reaction.Hei tauira, ka hangaia te acetyl acetate hei whakaputa i te acetyl ethyl acetate.He mea tino nui tenei tauhohenga ki te whakahiato waro.
Ko te ingoa o te hākawa i ahu mai i te ingoa ōrite o te waikawa carboxylic me te waipiro, te phenol ranei, penei i "tetahi waikawa me tetahi ester".Ko nga hākawa porowhita ka kiia ko te lactone (lactone).Ko nga ahuatanga matū o te hākawa he rite ki te amyl niche anhydride, he pai ki te hauwai, te waipiro me te tauhohenga haukini.Ko te hākawa-koeke iti he wai kakara, he wai kore tae, he totoka te hākawa matatau.Ko te Estes he whakarewa nui me nga rauemi mata waihanga, a ko etahi ester he raau taero.E ai ki te momo waikawa, ka taea te wehea te ester ki te ester waikawa pararopi me te ester waikawa waro.Ko te Etate, ko te ethyl acetate he ester ngako, ko te acetate he hākawa kakara, ko te namanonate he hākawa hurihanga.
Ko te hākawa he wai kore tae noa.Ko te hākawa i hangaia e te iwi momona me te waipiro kukū he kakara hua, ka taea te rewa ki te wai, he uaua hoki ki te memeha ki te wai.He iti te ira hiko o etahi ester, ka wera tonu.Ka taea te ngongo te mamaoa e te rewharewha o te manawa, ka taea hoki te haukawa wai e te kiri.I muri i te whakaurunga, ka memeha ki roto i te plasma, ka tukuna etahi o ratou ma nga ngongo me nga whatukuhu.Whai muri i etahi hauwai, ka huri ki roto i te tukanga metabolic noa.I tua atu i etahi o nga pūhui ester, he tino paitini, he tino paitini te nuinga, a ko te nuinga he moroiti -paitini ki nga waahanga paitini waenga, a ko te nuinga o aua mea he paitini kore.E 38 nga hākawa kei roto i nga roopu kakara o te ti.Ko te nuinga: ① te hākawa ngako: i hangaia e te waipiro me te ngako, penei i te ethyl acetate, hexyl hexyate.② Ester Aromatic: he mea hanga e te waipiro me te waikawa kakara, penei i te Shun-3-hexylzyl.③ Ko nga hākawa porowhita: he mea hanga e te waipiro me te motoka, penei i te hyacxide jasmone.Ko te hākawa i te nuinga o te wā he kūpapa, ka taea te hauwai me te whakaputa waipiro me te waikawa.Ko nga tau waro iti he wai kakara, ko nga tau waro teitei he wai, he totoka kore e rewa ki te wai.
