p-Anisic acid CAS:100-09-4

ʻO ka wehewehe pōkole:

ʻO ka p-Methoxybenzoic acid, ka mea i kapa ʻia ʻo 4-methoxybenzoic acid a i ʻole PMBA, he pauka crystalline keʻokeʻo no ka papa o nā derivatives benzoic acid.Hoʻohana nui ʻia ʻo ia ma ke ʻano he waena i ka synthesis o nā lāʻau lapaʻau, nā mea ʻala, nā mea ʻala a me nā kemika maikaʻi ʻē aʻe.Aia ka hui kemika o ka p-methoxybenzoic acid i kahi hui waikawa carboxylic i hoʻopili ʻia i ke apo benzene, e hāʻawi iā ia i nā waiwai kūʻokoʻa.

E hoʻouna i ka leka uila iā mākou

ʻO kekahi o nā hiʻohiʻona nui o ka p-methoxybenzoic acid ka maʻemaʻe kiʻekiʻe.Hoʻopili ʻia kā mākou huahana me ka hoʻohana ʻana i nā ʻenehana hana holomua e hōʻoia i ka maʻemaʻe haʻahaʻa o 99%.He mea koʻikoʻi kēia maʻemaʻe kiʻekiʻe, ʻoi aku hoʻi i nā ʻoihana e like me nā lāʻau lapaʻau a me nā mea hoʻonaninani kahi koʻikoʻi nā kūlana maikaʻi a me ka palekana.

Hoʻohui ʻia, hōʻike ka p-methoxybenzoic acid i ke kūpaʻa maikaʻi loa, e lilo ia i koho hilinaʻi no nā ʻano noi.ʻO ka helu heheʻe ma kahi o 199-201°C, hiki ke hoʻoheheʻe ʻia e like me ka ethanol, methanol, a me ka acetone.ʻO kona kūpaʻa e hiki ai i ka mālama maʻalahi a me ka mālama ʻana, e hōʻoia ana i ka lōʻihi o ka mālama ʻana a me ka liʻiliʻi o ka degradation.

I loko o ka ʻoihana lāʻau lapaʻau, p-methoxybenzoic acid kahi mea nui i ka synthesis o nā lāʻau lapaʻau ikaika (API).Hoʻohana nui ʻia i ka hana ʻana i nā lāʻau antihypertensive, anti-inflammatory drugs, local anesthetics, etc. ʻO kona hiki ke hana ma ke ʻano he precursor i kēia mau pūhui lāʻau lapaʻau nui e lilo ia i mea nui i ka noiʻi a me ka hoʻomohala ʻana i ka lāʻau.

Eia kekahi, hoʻohana pū ʻia ka p-methoxybenzoic acid i ke kahua o nā dyes a me nā puaʻa.ʻO kāna hana kemika hiki iā ia ke hana ma ke ʻano he mea hoʻohui no nā kala like ʻole, hoʻonui i ka wikiwiki o ka waihoʻoluʻu a hoʻomaikaʻi i ka maikaʻi o ke kala.Hoʻohui ʻia, hoʻohana ʻia i ka hana ʻana i nā mea ʻala ʻoiai e hāʻawi ana i kahi ʻala ʻoluʻolu a kōkua i ka hoʻopaʻa ʻana i nā pūhui ʻala.

i ka hopena:

I ka hopena, ʻo ka p-methoxybenzoic acid (CAS 100-09-4) he hui maʻemaʻe nui loa i hoʻohana nui ʻia i nā ʻoihana lāʻau lapaʻau, dye a me nā mea ʻala.ʻO kona mau waiwai kūikawā, e like me ke kūpaʻa kiʻekiʻe a me ka solubility, he koho maikaʻi loa ia no nā ʻano noi.Me kā mākou kūpaʻa i ka maikaʻi a me ka ʻoluʻolu o ka mea kūʻai aku, ke hōʻoiaʻiʻo nei mākou e hui a ʻoi aku kā mākou para-methoxybenzoic acid i kāu mau manaʻo.E kau i kāu kauoha i kēia lā a ʻike i nā pōmaikaʻi he nui i hāʻawi ʻia e kēia hui kūikawā.
