Kūlana Lahui o ka Waikawa Propionic (Nā Kikoʻī GB)
Ua wehewehe maopopo ke kūlana aupuni no ka waikawa propionic i kona ʻano: he wai moakaka, ʻaʻohe kala me kahi ʻala ʻawaʻawa, a pono e hoʻokō kona kala i nā kūlana colorimetric ʻike maka kikoʻī (e laʻa, me ka waiwai APHA ʻaʻole i ʻoi aku ma mua o kahi palena i kuhikuhi ʻia) e hōʻoia i ka hoʻokō ʻana o ka huahana i nā koi maikaʻi o ke ʻano.
Ma ke ʻano o ka maʻemaʻe, ke kauoha nei ke kūlana aupuni i ka liʻiliʻi o ka ʻike o ka waikawa propionic he 99.0%. Hōʻoia kēia koi maʻemaʻe kiʻekiʻe e hāʻawi ka waikawa propionic i ka hana paʻa a hilinaʻi hoʻi ma nā ʻano hana ʻoihana like ʻole a me nā hiʻohiʻona noi. ʻO ka ʻike wai kahi mea koʻikoʻi e pili ana i ka maikaʻi o ka huahana; e like me ke kūlana, pono e kāohi ʻia ka ʻike wai ma lalo o 0.5% e pale aku i ka makū nui mai ke komo ʻana i kona mau waiwai kemika a me ka hana. ʻO ka waikawa, ma ke ʻano he hōʻailona koʻikoʻi, ua wehewehe pono ʻia: ʻo ka waikawa (i hōʻike ʻia ma ke ʻano he hapa nui, i helu ʻia ma ke ʻano he waikawa propionic) pono e hāʻule i loko o kahi pae i wehewehe ʻia e hōʻoia i ka paʻa kemika o ka huahana a me ka reactivity e hoʻokō i nā koi. Ua kaupalena loa ʻia ka ʻike metala kaumaha ma ke kūlana—ua kaupalena ʻia ke kēpau, mercury, a me nā metala kaumaha ʻē aʻe i nā pae haʻahaʻa loa, i ana pinepine ʻia ma ppm (nā ʻāpana i kēlā me kēia miliona), e hōʻoia i ka palekana no ka hoʻohana ʻana i ka meaʻai, nā lāʻau lapaʻau, a me nā ʻoihana koʻikoʻi ʻē aʻe.
Hoʻokau pū ke kūlana aupuni i nā koi kikoʻī no ka nui. Ma kahi mahana i kuhikuhi ʻia (e laʻa, 20°C), pono e hāʻule ka nui i loko o kahi pae i wehewehe ʻia, e hōʻike ana inā kūlike nā waiwai kino o ka huahana me nā kūlana. ʻO ka pae paila kekahi mea nui e noʻonoʻo ai: pono ka waikawa propionic i kahi pae paila maʻamau o 140°C - 142°C, e hōʻoiaʻiʻo ana i kona kūpaʻa wela a me ka volatility e hoʻokō i nā koi ʻoihana like. Hoʻoponopono paʻa ʻia ka nui o ka Chloride, me ke kūlana e koi ana i nā pae chloride ma lalo o kahi paepae kikoʻī (e laʻa, 0.001%) e pale aku i nā hopena maikaʻi ʻole i ka maikaʻi o ka huahana a me ka hana ʻana ma hope. Aia pū kekahi mau palena maopopo o ka nui o ka hao, ʻaʻole ma mua o 0.0001%, e pale aku i nā mea hao e hoʻopilikia ana i ke kala, ke kūpaʻa, a me ka hana o ka waikawa propionic i kekahi mau noi kūikawā.
E pili ana i ka solubility, koi ke kūlana aupuni i ka propionic acid e hōʻike i ka solubility maikaʻi i nā solvents kikoʻī (e like me ka ethanol, diethyl ether), e ʻae ana i ka miscibility piha ma kekahi mau lakio e hoʻokō i nā koi formulation ma nā hiʻohiʻona noi like ʻole.

ʻO Shandong Pulisi Chemical Co., Ltd. kahi mea hana kūikawā a me ka mea hoʻolako o ka waikawa propionic kiʻekiʻe ma Kina, i hoʻolaʻa ʻia no ka hāʻawi ʻana i ka maʻemaʻe mau, ka lako hilinaʻi, a me nā hoʻonā i hana kūikawā ʻia no nā mea kūʻai aku ʻoihana honua. Hana ʻia kā mākou waikawa propionic ma lalo o nā kūlana GB/T 10615 paʻa, me ka maʻemaʻe kiʻekiʻe e hōʻea ana i ka ≥99.5% a me ka papa mua ma ≥99.0%, e hōʻike ana i ka makū haʻahaʻa, ka nui o ka hao haʻahaʻa, a me nā pae metala kaumaha i kāohi ʻia e hoʻokō i nā koi koi o nā noi hoʻohana hope like ʻole.
Hana ʻia ma o ka ʻenehana propylene oxidation holomua, hōʻoia kā mākou propionic acid i nā waiwai kemika paʻa, ka solubility maikaʻi loa, a me ka maikaʻi mau o ka batch ma hope o ka batch. Hana ia ma ke ʻano he kikowaena koʻikoʻi i ka synthesis organik, ka hana plastic, nā kaʻina hana electroplating, ka mālama ʻana i ka meaʻai a me ka meaʻai, a me ka hana lāʻau lapaʻau a me ka agrochemical. Kākoʻo ʻia e kā mākou keʻena hoʻomalu maikaʻi i loko o ka hale a me nā protocol hoʻāʻo piha, ua hele pū ʻia kēlā me kēia ukana me ka COA piha, MSDS, a me nā palapala hoʻokō ʻē aʻe e hoʻomaʻamaʻa i ka lawe ʻana mai a me ka hoʻohana ʻana ma ka honua holoʻokoʻa.
Me nā makahiki he nui o ka ʻike hoʻokuʻu aku i ʻAsia, ʻEulopa, ka Hikina Waena, a ma ʻō aku, hāʻawi mākou i nā koho hoʻopili maʻalahi, nā kumukūʻai hoʻokūkū, a me nā huaʻōlelo hoʻouna hilinaʻi e like me FOB, CIF, a me DDP. Inā makemake ʻoe i nā kauoha hoʻāʻo liʻiliʻi a i ʻole nā ​​​​lako nui, ua mākaukau kā mākou hui hoʻolaʻa e hāʻawi i ke kākoʻo loea pane a me ka lawelawe i hana ʻia e hoʻokō i kāu mau pono ʻoihana kūikawā.
