ʻO ka pauka ʻulaʻula. ʻO ka helu hoʻoheheʻe ma kahi o 200 ° C. Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, hiki ke hoʻoheheʻe ʻia i ka waikawa. Hiki ke pahū ke ʻike ʻia i ka wela, pili me ka lapalapa hāmama, wela kiʻekiʻe, friction, vibration, a me ka hopena. Ke puhi ʻia, hoʻopuka ʻo ia i nā uahi ʻawaʻawa a hoʻonāukiuki. Hiki i ka hui ʻana me nā oxidants ke hana i nā hui pahū.

Hoʻokuʻu ʻia ka hydrazine sulfate i ka wai wela, hoʻohui ʻia ka potassium acetate, hoʻomaʻalili ma hope o ka hoʻolapalapa ʻana, hoʻohui ʻia ka ethanol, kānana ʻia nā mea paʻa, a holoi ʻia ka filtrate me ka ethanol. 2,4-= nitrophenyl ethanol ua hoʻohui ʻia i ka hydrazine solution ma luna, a ua loaʻa ʻo 2,4-= nitrophenylhydrazine ma o ka kānana, holoi, hoʻomaloʻo, a me ka filtrate concentration.

hoʻohana

He chromogenic reagent ia no ka hoʻoholo ʻana i nā aldehydes a me nā ketones e ka chromatography layer thin. Hoʻohana ʻia ia e like me ka ultraviolet derivatization reagent no nā aldehydes a me nā ketones i ka synthesis organik a me ka hana pahū.

iole waha LDso: 654mg/kg. He mea hoʻonāukiuki i ka maka a me ka ʻili. He mea hoʻonanea i ka ʻili. Hoʻopili ʻia kēia huahana i loko o ke kino, hiki ke kumu i ka methemoglobinemia a me ka cyanosis. E kūʻai i loko o kahi hale kūʻai maʻalili. E mālama i ke ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka hale waihona ma mua o 30 ° C. Palekana mai ka lā pololei. E hoʻopaʻa paʻa i ka pahu. No nā kumu palekana, hoʻomaʻemaʻe pinepine ʻia a hoʻopaʻa ʻia me ka liʻiliʻi o 25% wai i ka wā mālama a me ka lawe ʻana. Pono e mālama kaʻawale ʻia mai nā oxidants a me nā waikawa. Mai hoʻohui i ka waiho ʻana a me ka lawe ʻana.
