3. Kaʻina Hana Kāpona Methanol
ʻO ka methanol carbonylation kahi ʻano hana hou no ka hana ʻana i ka waikawa propionic. Me ka hoʻohana ʻana i ka methanol ma ke ʻano he mea maka, hana ʻia ka hopena ma ke alo o kahi mea hoʻoulu e hana i kahi ʻōnaehana waena carbonyl i hoʻokumu ʻia i ka methanol, a laila hoʻomake ʻia e hana i ka waikawa propionic.
4. Kaʻina Hana ʻOkika Propylene
1. Hoʻomākaukau ʻana i nā mea maka
ʻO nā mea maka no ka hoʻomake ʻana o ka propylene e komo pū me ka propylene, ka ea, a me ka wai. Loaʻa ka propylene mai nā hale hoʻomaʻemaʻe a i ʻole nā ​​​​mea hana haki, ʻoiai ua loaʻa ka ea mai nā ʻāpana hoʻokaʻawale ea.
2. Kaʻina Hana
Hoʻomehana mua ʻana: Hoʻomehana mua ʻia ka propylene a me ka ea i nā mahana kūpono e hōʻoia i ka holo pono ʻana o ka hopena.
Hana Hoʻouluulu: Hoʻohui ʻia ka propylene a me ka ea i hoʻomehana mua ʻia a hana ʻia i ke alo o kahi mea hoʻouluulu. Hana ʻia kēia hana ma lalo o nā kūlana wela a me ke kaomi kiʻekiʻe, maʻamau ma 250-350°C a me 1-3 MPa.
Hoʻomaʻalili: Hoʻomaʻalili ʻia ka huahana hopena i ka mahana o ka lumi ma o kahi mea hoʻomaʻalili no ka hana hou aku.
3. Ka Hoʻokaʻawale ʻana a me ka Hoʻomaʻemaʻe ʻana
Ma hope o ka hopena, loaʻa i ka huahana nā nui o nā mea haumia a me nā mea maka i hana ʻole ʻia, e pono ai ka hoʻokaʻawale a me ka hoʻomaʻemaʻe ʻana:
Ka hoʻokaʻawale ʻana: Hoʻokaʻawale ʻia ka wai, ka propylene i hana ʻole ʻia, a me nā mea haumia ʻē aʻe mai ka huahana me ka hoʻohana ʻana i nā mea hoʻokaʻawale.
Hoʻomaʻemaʻe: Hoʻomaʻemaʻe ʻia ka waikawa propionic i hoʻokaʻawale ʻia ma o ka distillation, extraction, a me nā ʻano hana ʻē aʻe e loaʻa ai ka waikawa propionic maʻemaʻe kiʻekiʻe.

ʻO Shandong Pulisi Chemical Co., Ltd. kahi mea hoʻolako hilinaʻi a me ka mea hana o ka waikawa propionic kiʻekiʻe (CH₃CH₂COOH, CAS 79-09-4) ma Kina, e hāʻawi ana i nā huahana kūlana kiʻekiʻe i hana ʻia no nā ʻoihana ʻoihana, meaʻai, hānai, a me nā noi lāʻau lapaʻau. ʻO kā mākou waikawa propionic he wai ʻawaʻawa ʻole, me kahi ʻala ʻawaʻawa, e hōʻike ana i ka solubility kiʻekiʻe i ka wai a me nā mea hoʻoheheʻe organik, a me ke ʻano kūlike e kūlike me nā kūlana honua.
Hana ʻia ma o nā kaʻina hana oxidation holomua me ka kaohi maikaʻi koʻikoʻi, ua kūlike kā mākou waikawa propionic me nā kikoʻī o ka ʻoihana a me ka meaʻai, e hōʻoiaʻiʻo ana i ka haʻahaʻa o ka haumia a me ka hana paʻa. Hana ia ma ke ʻano he mea mālama koʻikoʻi, mea antifungal, a me ka mea waena kemika: hoʻohana nui ʻia i ka mālama ʻana i ka meaʻai (nā mea i hoʻomoʻa ʻia, nā huahana waiū), ka mālama ʻana i ka hānai a me ka palaoa (kāohi i ka ulu ʻana o ka ʻōpala), ka hana ʻana i nā paʻakai propionate (sodium propionate, calcium propionate), a me ka synthesis o nā herbicides, plasticizers, fragrances, a me nā mea waena lāʻau lapaʻau.
Ma Pulisi Chemical, hoʻoikaika mākou i ke kūpaʻa o ka huahana, ka palekana, a me ka lako hoʻomau. Hoʻopili ʻia kā mākou waikawa propionic i loko o nā pahu maʻamau a i ʻole nā ​​​​​​pahu ISO, me nā koho hoʻouna maʻalahi e hoʻokō i nā koi like ʻole o nā mea kūʻai aku honua. Kākoʻo ʻia e nā makahiki o ka ʻike hana kemika a me kahi hui R&D ʻoihana, hōʻoia mākou i ka maikaʻi o ka huahana kūlike, nā kumukūʻai hoʻokūkū, a me ke kākoʻo loea piha no nā hoa ma ka honua holoʻokoʻa.
