Hoʻolauna
ʻO ka 4,5-Dimethylthiazole kahi hui kūlohelohe. Eia kekahi o kāna mau waiwai, hoʻohana, hana hana, a me ka ʻike palekana.
ʻAno maikaʻi:
- Ke ʻano: wai waihoʻoluʻu a i ʻole crystalline solid.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona, ethers a me nā ketones.
- Paʻa: Paʻa ia i ka mahana wela.
E hoʻohana:
- Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe a me ka lāʻau vulcanizing lāʻau e hoʻomaikaʻi i nā waiwai mechanical o ka lāʻau.
Hanana:
- Hiki ke hana ʻia ka 4,5-Dimethylthiazole e ka hopena o ka dimethyl sodium dithiolate a me 2-bromoacetone.
- Ka hoohalike ana: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
ʻIke palekana:
- ʻO 4,5-Dimethylthiazole kahi hui kūlohelohe a pono e pale ʻia me nā ʻano hana kūpono.
- Pono nā mīkina lima pale, nā maka aniani a me nā ʻaʻahu i ka wā e hoʻohana ai.
- Hōʻalo i ka hoʻohu ʻana i kāna mau mahu a hōʻoia i ka hana ʻana ma kahi ʻano maikaʻi-ventilated.
- I ka wā o ka paʻi ʻana i nā maka, holoi koke me ka wai nui a ʻimi koke i ke kauka.
- E mālama i ka 4,5-dimethylthiazole ma kahi maloʻo a maloʻo ma kahi mamao o nā mea ʻona a me nā waikawa ikaika.
