Hoʻolauna
3,5-Dimethylbenzoic acid. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: paʻa kala kala ʻole;
- ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai a ʻoi aku ka hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ethers a me nā waiʻona;
- He ʻala ʻala.
E hoʻohana:
- 3,5-Dimethylbenzoic acid he mea koʻikoʻi i waena o ka synthesis organik a hoʻohana pinepine ʻia i ka synthesis o nā mea hoʻohui ʻē aʻe;
- Hiki ke hoʻohana ʻia e like me ka mea maka no nā resins polyester a me nā uhi, nā plastics a me nā mea hoʻohui;
Hanana:
- Hiki ke loaʻa ke ʻano hoʻomākaukau o ka 3,5-dimethylbenzoic acid ma ka hopena o benzaldehyde me ka dimethyl sulfide;
- Hoʻokō pinepine ʻia nā hopena ma lalo o nā kūlana acidic, a hiki ke hoʻohana ʻia nā catalysts acidic e like me hydrochloric acid;
- Ma hope o ka hopena, loaʻa ka huahana maʻemaʻe e ka crystallization a i ʻole ka unuhi ʻana.
ʻIke palekana:
- Pono e hoʻohana ʻia ka hui e like me nā protocol laboratory kūpono;
- Hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōnaehana hanu;
- E ʻaʻahu i nā mea pale pilikino, e like me nā mīkina lima lima a me nā maka aniani, a e hōʻoia i ka ea maikaʻi ke hoʻohana ʻia;
- Hōʻalo i ka hoʻopili ʻana me nā mea oxidizing ikaika a me nā waikawa ikaika;
- E mālama i kahi maloʻo, hoʻopaʻa paʻa ʻia, a pale aku i ka pili ʻana me ka ea, ka makū, a me ke ahi.
I ka hoʻohana ʻana i ka 3,5-dimethylbenzoic acid a i ʻole nā mea ʻē aʻe, he mea nui ia e hahai i ka mālama ʻana i nā kemika kūpono a me nā hana palekana.
