Ethyl 3-Mercaptopropionate（CAS#5466-6-8）
kino:
ʻAno: ʻAʻole waihoʻoluʻu i ka wai aniani melemele māmā me kahi ʻala kūikawā.
Lae paila: ʻO ka maʻamau ma 190 – 192 °C (ma ke kaomi ʻana i ka lewa maʻamau), ʻokoʻa iki ka pae hoʻolapalapa ma muli o nā kūlana hoʻokolohua a me ka maʻemaʻe.
Density: ʻO ka mānoanoa pili ma kahi o 1.07 (wai = 1), ʻo ia hoʻi, ʻoi aku ke kaumaha ma mua o ka wai a i ka wā mālama a hoʻohana ʻia, aia ia ma ka papa haʻahaʻa inā hui pū me ka wai.
Solubility: hiki ke hoʻoheheʻe iki i ka wai, akā hiki ke hui pū me ka hapa nui o nā mea hoʻoheheʻe organik e like me ka ethanol, ether, acetone, a me nā mea ʻē aʻe.
Nā waiwai kemika:
Hoʻoikaika pūʻulu hana: ʻO ka pūʻulu sulfhydryl (-SH) i loko o ka mole ke ʻano ikaika a ʻo ia ke kahua ikaika o nā hopena kemika. Hiki iā ia ke hana i ka hopena condensation me nā pūhui carbonyl e like me nā aldehydes a me nā ketones e hana i nā pūhui thioether; Hiki iā ia ke hana i nā hoʻololi hoʻololi me nā hydrocarbons halogenated e hana i nā mea paʻa kalapona-sulfur hou, hiki ke hoʻohana ʻia no ke kūkulu ʻana i nā hale molekala ʻano paʻakikī.
Paʻa: He kūpaʻa ma ka lumi wela a me ke kaomi, akā ma lalo o nā kūlana o ka mālamalama, ke kiʻekiʻe o ka mahana a i ʻole ke alo o nā mea ʻokiʻoki ikaika, hiki ke hoʻoneʻe ʻia nā pūʻulu sulfhydryl, e hopena i nā loli i nā waiwai kemika o nā pūhui, no laila pono lākou e e mālama ʻia a hoʻohana ʻia ma lalo o nā kūlana kūpono, a ʻoi aku ka maʻamau e mālama i kahi ʻoluʻolu, ventilated a me ka pōʻeleʻele, a pale i ka hoʻopili ʻana me nā oxidants ikaika.
Hana Hana:
Hoʻomākaukau maʻamau ia e ka esterification o 3-mercaptopropionic acid me ka ethanol i mua o kahi catalyst acidic e like me ka sulfuric acid concentrated. I ka wā o ka hopena, ʻo ka mea mua, ʻo ka hui carboxyl a me ka pūʻulu hydroxyl o ka ethanol e loaʻa i kahi hopena nucleophilic substitution ma lalo o nā kūlana acidic e hana i nā paʻa ester, a i ka manawa like e hana ʻia ka wai. I ka pau ʻana o ka hopena, pono e hoʻomaʻemaʻe ʻia ka huahana ma o nā ʻanuʻu post-processing e like me ka neutralization, ka holoi wai, a me ka distillation no ka loaʻa ʻana o ka Ethyl 3-Mercaptopropionate kiʻekiʻe.
E hoʻohana:
Kahua ʻala: He ʻala ʻokoʻa kona a hoʻohana ʻia ma ke ʻano he waena o nā mea ʻala synthetic i loko o ka ʻoihana ʻala, hiki ke hoʻohui i ka ʻono kūikawā a me ka waiho ʻana i nā mea ʻala i hui ʻia, a hoʻohana pinepine ʻia e hoʻohui i nā ʻono e like me nā huaʻai a me nā ʻiʻo e hoʻokō i nā pono. ʻO ka meaʻai, nā mea hoʻonaninani a me nā ʻoihana ʻē aʻe no ka hoʻololi ʻana i ka ʻala.
Kahua lāʻau lapaʻau: Hiki ke hoʻohana ʻia ma ke ʻano he kumu kumu a i ʻole waena i ka synthesis lāʻau lapaʻau e kūkulu i nā hale molekala me nā hana koʻikoʻi. No ka laʻana, i ka synthesis o kekahi mau lāʻau i loaʻa i ka sulfur, hiki ke hoʻokomo ʻia kā lākou mau pūʻulu sulfhydryl i loko o ka mole i hoʻopaʻa ʻia ma o nā hopena kemika, a laila e hāʻawi i nā hana pharmacological kikoʻī i ka lāʻau, e like me ka antioxidant, antimicrobial, a i ʻole ka hoʻoponopono ʻana i ka hana enzyme.
Mahiai: Loaʻa iā ia kekahi noi i ka synthesis o nā pesticides, ma ka hoʻololi ʻana i kona ʻano molekala a me ka hoʻokomo ʻana i nā pūʻulu hana kūikawā, i hiki iā ia ke hōʻike i nā hopena hoʻomalu maikaʻi i nā mea ʻeha a i ʻole nā patogen i nā mea kanu, e kōkua ana i ka hoʻomaikaʻi ʻana i ka hua a me ka maikaʻi o nā mea kanu. a e hōʻoia i ka paʻa o ka hana mahiʻai.
