Hoʻolauna

ʻAno maikaʻi:

- Ke ʻano: He wai kala ʻole ʻo Benzoaldehyde, akā melemele nā ​​laʻana kālepa maʻamau.

- Aʻala: He ʻala ʻala.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ʻo Benzoaldehyde ma o ka hoʻohemo ʻana i nā hydrocarbons. ʻO nā ʻano hana hoʻomākaukau maʻamau e like me kēia:

- Oxidation mai phenol: Ma ke alo o kahi catalyst, ua hoʻoheheʻe ʻia ka phenol e ka oxygen i ka lewa e hana i benzaldehyde.

- Catalytic oxidation mai ka ethylene: Ma ke alo o ka catalyst, hoʻoheheʻe ʻia ka ethylene e ka oxygen i ka lewa a lilo i benzaldehyde.

 

ʻIke palekana:

- He haʻahaʻa haʻahaʻa kona ʻona a ʻaʻole e hoʻokau i nā pilikia olakino koʻikoʻi i nā kānaka ma lalo o nā kūlana maʻamau o ka hoʻohana.

- He mea hoʻonāukiuki i ka maka a me ka ʻili, a pono e lawe ʻia nā mea pale e like me nā mīkina lima a me nā maka aniani ke hoʻopā.

- ʻO ka hoʻolōʻihi ʻia ʻana i nā kiʻekiʻe kiʻekiʻe o ka mahu benzaldehyde hiki ke hoʻonāukiuki i ka ʻōpū hanu a me nā akemāmā, a pono e pale ʻia ka inhalation lōʻihi.

- I ka lawelawe ʻana i ka benzaldehyde, pono e mālama ʻia i ke ahi a me ke ʻano o ka ea e pale aku i ka ʻike ʻana i nā lapalapa ahi a i ʻole nā ​​wela kiʻekiʻe.
