2-Methyltetrahydrofuran (2-MeTHF) he wai bio-ma muli o ke ahi, akaka, a hiki loa ke ahi me ka eter-ala, i hoohana mau ia ma ke ano he mea hoohehee iloko o ka hana hoano. ʻO ka lawelawe ʻana ma ke ʻano he pani hoʻomau no nā mea hoʻoheheʻe kuʻuna e like me tetrahydrofuran (THF) a me dichloromethane, hāʻawi ia i nā pōmaikaʻi he nui: ʻoi aku ka nui o ka paila ʻana, ka haʻahaʻa haʻahaʻa o ka wai, hoʻemi ʻia ka ʻawaʻawa, a me ka hoʻomaikaʻi ʻana i ka hana ma nā hopena ʻelua a me nā unuhi. Me ka hoʻokō maikaʻi loa me nā organometallic reagents a me kahi laula hoʻoheheʻe ākea, 2-MeTHF mea waiwai nui i ka hana lāʻau lapaʻau, ʻoi aku ka nui o ka synthesis o nā mea hana lāʻau paʻakikī (API). Pili kaiapuni a hiki ke hana hou ia, ua kulike ia me na loina kemika omaomao a ua kupono no ka hoohana ana i ka unahi-labora a me ka unahi hana.

1. Hoʻomaikaʻi i ka koho koho a me ka hua
Hiki i nā haumia (e like me ka wai, peroxides, alcohols, a me aldehydes) ke hoʻopilikia i nā catalysts a i ʻole substrates, e alakaʻi ana i nā hopena ʻaoʻao. Ma ka ho'ohana 'ana i ka -ma'ema'e ki'eki'e 2-MeTHF e ho'opa'a 'ia ai nā kūlana ho'ololi pa'a, 'oi aku no ka ho'opa'a ma'ema'e (e la'a, Grignard a i 'ole organolithium reactions).
2. Hoʻonui i ka hana Catalyst
Hiki i nā haumia ke hoʻomake a hoʻopau paha i nā catalysts, ʻoi aku ka metala -mea (e laʻa, Pd, Ni, Cu). Hiki i ka -ma'ema'e ki'eki'e ka 2-MeTHF e ho'olō'ihi i ke ola o ka catalyst, e ho'emi i ka ho'ouka 'ana i ka catalyst, a e ho'emi i ke koina.
3. Hoʻomaikaʻi i ka hana hou a me ka Scalability
Hiki i ka ho'oma'ema'e 'olu'olu 'ole ke alaka'i i ka 'ano like 'ole o ka hui-a-pu'upu'u ma waena o ka hana ho'okohu -a me ka hana 'oihana. ʻO ka hoʻohana ʻana i nā mea hoʻoheheʻe maʻemaʻe kiʻekiʻe e hōʻoiaʻiʻo i ka mana kaʻina hana ʻoi aku ka maikaʻi a me ka hana hou ʻana, e pili ana i nā kūlana hana GMP a me nā lāʻau lapaʻau.
4. E hoemi ana i ka pilikia o na hua mahuahua
Hiki i kekahi mau mea haumia ke hana me nā mea waena e hana i nā pūhui paʻa ʻole a i ʻole nā pilikia, e hoʻonui ana i nā pilikia palekana. Hoʻemi ʻia ka -maʻemaʻe kiʻekiʻe 2-MeTHF i ia mau pilikia, e hōʻoia ana i nā hopena palekana a ʻoi aku ka maikaʻi o ke kaiapuni.

FAQ
Nīnau: No ke aha he mea nui ka -maʻemaʻe kiʻekiʻe 2-MeTHF i ka hoʻohui lāʻau?
A: Kiʻekiʻe -maʻemaʻe 2-MeTHF e hōʻoia i ka ʻoi aku ka maikaʻi o ke koho ʻana, ka hana catalyst, a me ka hana hou ʻana, ʻoi aku hoʻi i loko o nā hopena ʻeleʻele e like me Grignard a i ʻole organolithium synthesis.
Nīnau: Pehea e kākoʻo ai ka -maʻemaʻe kiʻekiʻe 2-MeTHF i ka kemika ʻōmaʻomaʻo?
A: He mea bio-mea hiki ke hana hou ia, haahaa i ka peroxides a me ka wai, a e hoemi ana i na mea hoowahawaha weliweli, e kulike ana me na hana kemika omaomao a hoomau.
Q: No ke aha e koho ai iā Shandong Yino?
A: 1. Hoʻolako paʻa a me ka maikaʻi
ʻO nā mea maka o 2-methyltetrahydrofuran, furfural a me 2-methylfuran, ʻo kā mākou huahana kālepa. Hoʻopaʻa mākou i kahi lako paʻa (ka puka makahiki o 15,000 tons, ka mea hana 2-methyltetrahydrofuran nui loa o ka honua); ʻO ka hana pono'ī o nā mea maka e hiki ai iā mākou ke hoʻomalu maikaʻi i ka paʻa o ka maikaʻi.
2. He kūʻokoʻa ka ʻoihana hoʻomalu maikaʻi i ka hale hana a mālama pono i ka maikaʻi
3. Ua uhi ka ʻoihana i ka honua, aia nā ʻelele ma nā awa a puni ka honua, a ua ʻae ʻia nā ʻōlelo kālepa like ʻole.
4. E nānā i ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau
Aia kekahi pūʻulu piha o ke kinoea ʻōpala, ka wai ʻōpala, a me ka mālama ʻana i ke koena o ka ʻōpala, a me ka hana hou ʻana iā lākou e hana i ka uila.
