Hoʻohana
Hoʻohana ʻia ʻo Benzaldehyde ma ke ʻano he waena i ka hana ʻana i nā kemika ʻono, e like me ka cinnamaldehyde, cinnamalalcohol, a me ka amyl- a me hexylcinnamaldehyde no ka mea ʻala, ke kopa, a me ka ʻono meaʻai; penicillin synthetic, ampicillin, a me ka ephedrine; a ma ke ʻano he mea maka no ka herbicide Avenge. Loaʻa ia ma ke ʻano maoli i loko o nā hua o nā ʻalemona, nā ʻapelika, nā cherry, a me nā peach. Loaʻa ia i loko o nā nui i loko o ka ʻaila kulina.
Hana ʻana i nā mea hoʻoluʻu, nā mea ʻala, nā waikawa cinnamic a me mandelic, ma ke ʻano he mea hoʻoheheʻe; i nā mea ʻono.
He mea ʻono ʻo Benzaldehyde, he wai a ʻaʻohe kala, a he ʻala like me ka ʻalemona. He ʻono wela (puhi) kona. Hoʻoheheʻe ʻia ia i ka waikawa benzoic ke hōʻike ʻia i ka lewa a palaho ma lalo o ka mālamalama. Hiki ke hui pū ʻia i loko o nā aila volatile, nā aila paʻa, ka ether, a me ka waiʻona; he mea hoʻoheheʻe iki ia i ka wai. Loaʻa ia ma o ka synthesis kemika a ma o ka hanana kūlohelohe i loko o nā aila o ka ʻalemona ʻawaʻawa, ka peach, a me ka ʻāpana apricot. Ua kapa ʻia hoʻi ʻo ia he benzoic aldehyde.
Ka hoʻopili ʻana
200KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
