Mazgu ghakwamba ghakukwana
2-Methyltetrahydrofuran (2-MeTHF) ni chinthu chakugwira ntchito chomene, chakupangika na vyamoyo ivyo vikupangika na Shandong Yino Biologic Materials Co., Ltd. vyakupangika nga ni vikumba vya chimanga na bagasse ya mijuwa - kupangiska kuti viŵe vyakwenelera chomene ku vilato vya mazuŵa ghano vya chemistry vyakukhaliska. Na msinkhu wa kutentha wa 79℃, kusungunuka kwa maji kwakucepa, na kukolerana kwakufwatuka, 2‐MeTHF yithu yikupereka mpaka 99.5% ya kutozga ndipo yili na Pachoko panji yakuyana na 10 ppm ya peroxides chifukwa cha kusazgirapo kwa BHT stabilizer. Kulinganizga na tetrahydrofuran (THF) yakale, njakuvikilirika, yikukhazikika pa kutentha, ndipo yikuperekaso 44% ya carbon. Kweniso, chifukwa chakuti pachaka tikupanga matani 15,000, tikuwoneseska kuti pa charu chose pali vyakurya vyakugomezgeka.
Mu vyakuchitika vya Grignard, 2‐MeTHF yikuwoneka nadi. Kukolerana kwake kwakufwatuka kukukhozga ntchito ya Grignard reagents - kovwira kukankhira vipambi mpaka 98% - uku kukuzizipizgaso maji ghachoko waka ( Pachoko panji ghakuyana na 0.1%), ivyo vikung'anamura kuti palije kukhumbikwa kwa nyengo zakuwomira chomene. Ndipo chifukwa chakuti yikupanga azeotrope na maji, viŵelengero vyakupokera vyakusungunuka vingafika pa 85%, kuchepeskako ndalama mu ndondomeko. Nthowa iyi yakusungunura vinthu yakupambanapambana yikagwiliskirika kale ntchito pakupanga munkhwala wakukoma maleriya wakuchemeka chloroquine phosphate, kupanga vinthu vya OLED, na kugwiliskira ntchito vinthu vinyake vinandi. Kufuma pa vyakupangika vya munkhwala m’paka pa vyakupangika na mabatire gha muwiro wakulondezgapo na mapulasitiki agho ghakuvunda, 2‐MeTHF yikovwira makampani pa charu chose kuti ghaŵe na vyakupangika vyakwenelera, vyakuvikilirika, ndiposo vyakubiriŵira nadi.

Kugwiriskira ncito & Ntchito yakuzirwa ya 2-methyltetrahydrofuran CAS 96-47-9.
1. Munthu uyo wakupanga vyakusungunura vyakubiriŵira: vyakupangika na 2-methyltetrahydrofuran
A bio-based solvent designed specifically for Grignard reactions with >99.5% kutozga na 44% kuchepa kwa carbon footprint, kovwira makasitomala a pharma / magesi kuti ŵasinthe nchito ya kupanga vinthu na ESG.
2. Uwemi wa umo Grignard wakuchitira vinthu
| Vinthu vyakugwiriskira ncito | 2-MeTHF vyakuchitika | Malo ghakuŵinya gha vyakusungunura vya chikhalidwe |
| Ntchito ya reagent | Kukolerana kwakufwatuka → Chipangizo cha Grignard chikupereka 98% ↑ | THF ili na katundu wankhongono wakukolerana (kupanga 92%) |
| Kuzizipizga chinyezi | Mungaŵa na maji ghachoko waka (Pafupi panji ghakuyana na 0.1% ghachali ghakukhazikika) | Ether wakwenera kuŵa wambura maji (nchakusuzga yayi kuzima) |
| Post-kupanga makora | Kupanga azeotrope na maji → nchakusuzga yayi kusangaso mwa kuŵika vinthu mu vigaŵa | THF yikusakanizgika chomene → mtengo ukuru wa kuseŵezeskaso |
| Walonda | Sazgilanipo BHT → Ngozi ya peroxide ↓ 90% | Ether wakuphulika → Kuvikilira na nayitrogeni kukukhumbikwa . |
3. Milandu yakugwiriskira ncito: Kusazgako vya pakati pa munkhwala:
Pakupanga munkhwala wakukoma maleriya wa primaquine phosphate, 2-MeTHF yikanjira mu malo gha ether nga ni vyakusungunura vya Grignard, nyengo yakuchitira vinthu yikafupikizgika na 40%, ndipo kutowa kwa primaquine kukakwera kufika pa 99.8%.

Mafumbo ghakufumbika
F: Kasi 2-MeTHF yili na vitumbiko wuli mu vyakuchitika vya Grignard pakuyaniska na vyakusungunura vya chikhalidwe?
A: Iwo ukupangiska kuti Grignard reagent yiŵe na 98% +, yikulekelera maji ghakulondezgapo ( Pachoko panji ghakuyana na 0.1%), yikupangiska kuti solvent yiŵeso yiwemi, ndipo yikuchepeska ngozi ya peroxide.
F: Kasi ni vichi ivyo vikupangiska kuti 2-MeTHF yigwiriskike nchito?
A: Ikukhwaska munkhwala, vinthu vya OLED, magesi ghaphya gha mabatire gha nkhongono, mapulasitiki ghakuvunda, na vinyake.
F: Chifukwa wuli mukusankha Shandong Yino?
A: 1. Kupereka kwakukhazikika na khalidwe
Vinthu vyambura kupangika vya 2-methyltetrahydrofuran, furfural na 2-methylfuran, ni vinthu ivyo tikuguliska. Tikugomezga kuti paŵenge vinthu vyakukwana (pachaka ŵakupanga matani 15,000, ndipo ŵakupanga 2-methyltetrahydrofuran chomene pa charu chose); kujipangira kwa vyakupangira vyakupangiraso kukutizomerezga kuti tiwone makora kukhazikika kwa mtundu.
2. Dipatimenti yakuwonelera mtundu wa vinthu yikujiyimira payokha ku fakitare ndipo yikulaŵilira chomene mtundu wa vinthu .
3. Bizinesi iyi yikukhwaska charu chose, pali ŵateŵeti mu madowoko pa charu chose, ndipo mazgu ghakupambanapambana gha malonda ghakuzomerezgeka .
4. Kuŵika mtima pa kuvikilira chilengiwa na chitukuko chakukhaliska .
Pali mtundu wose wa gasi lakuvunda, maji ghakuvunda, na vyakuvunda ivyo vyakhalako, na kuvigwiliskira ntchitoso kuti vipangiske magesi.
