1. Paʻa ma lalo o ka mahana maʻamau a me ke kaomi. ʻO nā mea kūpono ʻole: nā waikawa, nā alkali, nā mea hoʻohaʻahaʻa, nā mea hoʻoneʻe. He ʻano haʻahaʻa ʻona. E pale i ka hanu ʻana i ka mahu a me ka pili ʻana me ka ʻili.
Nā waiwai kemika: He poni ke hui me ka ferric chloride. Ke hoʻoheheʻe ʻia me ka dilute acid a i ʻole dilute alkali, hana ʻia ka acetone, ethanol a me carbon dioxide. Ma lalo o ka hana a kahi kumu ikaika, hana ʻia ʻelua mau mole o ka acetic acid a me ka ethanol. Ke hoʻemi ʻia ka catalytic, hoʻokumu ʻia ka β-hydroxybutyric acid. I loko o ka ethyl acetoacetate hou i hoʻoheheʻe ʻia, ʻo ke ʻano enol he 7% a ʻo ke ʻano ketone he 93%. I ka wā i hoʻomāʻalili ʻia ka hopena ethanol o ka ethyl acetoacetate i -78 ° C, ua hoʻoheheʻe ʻia ka hui ketone ma kahi kūlana crystalline. Inā hoʻokuʻu ʻia ka derivative sodium o ka ethyl acetoacetate i ka dimethyl ether a hoʻemi iki ʻia ka nui o ke kinoea hydrogen chloride maloʻo maloʻo ma -78°C, hiki ke loaʻa kahi hui enol ʻaila.
2. ʻAʻole ʻawaʻawa kēia huahana, waha iole LD503.98g/kg. Akā me ka huhū haʻahaʻa a me ka anesthesia, pono e hoʻopaʻa ʻia nā mea hana a hoʻopaʻa maikaʻi ʻia. Hoʻolakoʻia nā mea hana me nā mea pale.
