Hoʻolauna
ʻO 3,5-Dichloro-4-hydroxybenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 3,5-Dichloro-4-hydroxybenzoic acid he kala ʻole i ka pauka crystalline keʻokeʻo.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik e like me nā ʻawaʻawa a me nā etera, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
Hanana:
- Hiki ke loaʻa ka 3,5-Dichloro-4-hydroxybenzoic acid ma ka chlorination o ka parahydroxybenzoic acid. ʻO ke ala kikoʻī, ʻo ia ka hoʻopili ʻana i ka waika hydroxybenzoic me ka thionyl chloride e hoʻololi i ka atom hydrogen ma ka hui hydroxyl me nā ʻātoma chlorine ma lalo o nā kūlana acidic ma o ka hoʻololi ʻana i nā ion chloride.
ʻIke palekana:
- Nā hopena i ke olakino kanaka: 3,5-dichloro-4-hydroxybenzoic acid ʻaʻohe pōʻino i ke olakino kanaka ma lalo o nā kūlana maʻamau o ka hoʻohana.
- Hōʻalo i ka pili ʻana: I ka wā e lawelawe ai i kēia pūhui, e pale i ka hoʻopili pololei ʻana ma waena o ka ʻili a me nā maka a e hōʻoia i ka hana ʻana ma kahi wahi e hoʻoheheʻe maikaʻi ʻia.
- Pono e mālama ʻia ma kahi maloʻo, ʻoluʻolu, a me ka ea, ma kahi mamao o ke ahi a me nā mea puhi.
