Hoʻolauna
ʻO 4-Chloro-4′-hydroxybenzophenone kahi mea hoʻohuihui. Eia ka ʻike e pili ana i nā waiwai, nā hoʻohana, nā ʻano hoʻomākaukau, a me ka palekana o ka pūhui:
ʻAno maikaʻi:
ʻIke: 4-Chloro-4′-hydroxybenzophenone he keʻokeʻo keʻokeʻo a i ʻole ka pauka crystalline.
Hiki ke hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i ka ethanol, dimethylformamide a me ka chloroform, hiki ke hoʻoheheʻe iki ʻia i ka etera a me ka carbon chloride.
E hoʻohana:
Hiki ke hoʻohana ʻia ka 4-Chloro-4′-hydroxybenzophenone ma ke ʻano he waena i ka synthesis organik no ka hoʻohui ʻana o nā mea hoʻohui ʻē aʻe.
Hanana:
Hiki ke loaʻa iā 4-Chloro-4′-hydroxybenzophenone ma ke pani ʻana i ka sodium sulfite me ka sodium thiothioreagent (eg, phthathiadine) o ka sodium sulfite. ʻO ke ʻano hoʻomākaukau kūikawā penei:
Hoʻoheheʻe ʻia ka phthamethamidine i ka dimethylformamide, hoʻohui ʻia ka hydroxyacetophenone i ka hopena hopena, ma hope o kekahi manawa o ka hopena, hoʻohui ʻia ka wai, a lawe ʻia ka huahana, maloʻo a crystallized me ka chloroform e loaʻa ai ka huahana i manaʻo ʻia.
ʻIke palekana:
ʻO 4-Chloro-4′-hydroxybenzophenone ka mea paʻa ma lalo o nā kūlana maʻamau. Eia naʻe, pono e pale ʻia ka launa pū ʻana me nā mea hoʻoneʻe ikaika.
Pono e ʻaʻahu ʻia nā lako pale pilikino e like me nā mīkina lima, nā maka aniani, a me nā ʻaʻahu i ka wā e hana ai ia mau hana.
Pono e hoʻokaʻawale ʻia mai nā mea hiki ke hoʻopau ʻia a me nā kumu wela, a mālama ʻia i loko o kahi pahu paʻa i mea e pale aku ai i ka ea.
E ʻoluʻolu e hoʻolei pono i ka ʻōpala a me kāna ʻōpala, me ka hahai ʻana i nā lula hoʻokele kūloko.
