Hoʻoheheʻe ʻia ka wai m-toluic i ka wai?

m-toluic acidHe aniani keʻokeʻo a melemele paha, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka wai paila, hiki ke hoʻoheheʻe ʻia i ka ethanol, etera. A me ke kumu molekala C8H8O2 a me ka helu CAS 99-04-7. Hoʻohana maʻamau ia i nā ʻoihana like ʻole no nā kumu like ʻole. Ma kēia ʻatikala, e ʻimi mākou i nā waiwai, hoʻohana, a me ka solubility o ka waika m-toluic.

Nā waiwai o ka waika m-toluic:
m-toluic acidhe mea ʻala iki, keʻokeʻo keʻokeʻo paʻa me ka helu heheʻe o 105-107°C. Hiki ke hoʻoheheʻe ʻia i ka wai, a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka waiʻona, benzene, a me ka etera. ʻO ke kinona o ka waika m-toluic kahi apo benzene me kahi hui carboxyl -COOH i hoʻopili ʻia i ke apo ma ke kūlana meta. Hāʻawi kēia hoʻonohonoho hoʻonohonoho i ka m-toluic acid i nā waiwai like ʻole a me nā hoʻohana.

ʻO ka hoʻohana ʻana i ka waika m-toluic:
m-toluic acidhe kemika koʻikoʻi koʻikoʻi i hoʻohana ʻia ma nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā plastics, a me nā mea pena. Hoʻohana nui ʻia ia i ka hana ʻana i ka metolachlor, kahi herbicide koho i hoʻohana ʻia no ka hoʻopaʻa ʻana i nā nāhelehele i ka kulina a me ka soybeans. He kuleana koʻikoʻi ka m-toluic acid i ka synthesis o ka metolachlor, e pili ana i ka hopena o ka waika m-toluic me ka thionyl chloride e hana ai i waena e hana hou ʻia e hana i ka huahana hope.

ʻO kekahi hoʻohana ʻana i ka waika m-toluic i ka hana ʻana i nā polymers e like me nā polyamides a me nā resins polyester. Hoʻohana ʻia kēia mau polymers i ka hana ʻana i nā huahana like ʻole e like me ka textiles, plastics, a me nā adhesives. ʻO ka m-toluic acid kahi mea nui i ka hoʻohui ʻana o kēia mau polymers, kahi e hana ai ʻo ia ma ke ʻano he monomer e pili ana me nā molekole ʻē aʻe e hana i ke kaulahao polymer.

Solubility o ka waika m-toluic:
m-toluic acidhiki ke hoʻoheheʻe ʻia i loko o ka wai, ʻo ia hoʻi e hoʻoheheʻe ʻia i loko o ka wai i kahi palena palena. ʻO ka solubility o ka m-toluic acid i loko o ka wai ma kahi o 1.1 g/L i ka mahana wela. Hoʻopili ʻia kēia solubility e nā mea like ʻole e like me ka mahana, ka pH, a me ka loaʻa ʻana o nā solutes ʻē aʻe i loko o ka solvent.

ʻO ka hiki ke hoʻoheheʻe ʻia o ka waika m-toluic i loko o ka wai ma muli o ka loaʻa ʻana o ka hui carboxyl i kona ʻano. ʻO ka hui carboxyl he pūʻulu hana polar e launa pū me nā mole wai ma o ka hoʻopaʻa hydrogen. Eia nō naʻe, ʻo ke apo benzene i loko o ka waika m-toluic he nonpolar, kahi e hoʻokuke ai i nā molekole wai. Ma muli o kēia mau waiwai kū'ē'ē, ua li'ili'i ka solubility i ka wai m-toluic acid cas 99-04-7.

Ka hopena:
m-toluic acid cas 99-04-7he kemika koʻikoʻi waena me nā ʻano hana ʻoihana like ʻole. Hoʻohana ʻia ka m-toluic acid cas 99-04-7 i ka synthesis o metolachlor, polyamides, a me nā resins polyester. ʻOiai ʻo kona koʻikoʻi i kēia mau ʻoihana, ua kaupalena ka waika m-toluic acid i ka wai. ʻO kēia waiwai ma muli o ke ʻano paio o kona mau pūʻulu hana polar a me nonpolar. Eia naʻe, ʻaʻole pili ka haʻahaʻa haʻahaʻa o ka m-toluic acid i kona pono i nā ʻoihana e lawelawe ai.
