ʻO ke ʻano hana hoʻoheheʻe ʻana o ka waikawa Ethylene Glycol Nitric o ka waikawa Oxalic
Ua like loa kēia kaʻina hana hoʻomakeʻe me ke ʻano hoʻomakeʻe starch. Hoʻomehana ʻia kahi hopena ethylene glycol wai i 60 °C, a hoʻohui ʻia ka waikawa i hui ʻia (30%–40% sulfuric acid ma ke kaumaha, 20%–25% nitric acid ma ke kaumaha) a me ka vanadium pentoxide ma lalo o ka hoʻoulu ikaika. Hana ʻia ka hoʻomakeʻe ma 50–70 °C a me 1.3–4.0 kPa. Hoʻomaʻalili ʻia ka huahana, hoʻoheheʻe ʻia, a kānana ʻia e loaʻa ka waikawa oxalic me ka maʻemaʻe o 99.9% a me ka hua ma luna o 90%. Hiki ke hana ʻia kēia ʻano hana ma lalo o ʻekolu mau kūlana hana: kaomi lewa, kaomi hoʻemi, a me ke kaomi hoʻonui. He hana maʻalahi kona, hua waikawa oxalic kiʻekiʻe, maikaʻi ka maikaʻi o ka huahana, a kokoke i ka hoʻōla piha ʻana o ka waikawa nitric, akā kiʻekiʻe ke kumukūʻai o nā mea maka.

ʻO Shandong Pulisi Chemical Co., Ltd. ʻO ka ʻakika Oxalic Dihydrate - Papa ʻoihana 99.6% Maʻemaʻe
ʻO Shandong Pulisi Chemical Co., Ltd., kahi mea hana kemika hilinaʻi a me ka mea hoʻopuka aku mai ka makahiki 2006, loea i ka hana ʻana i ka oxalic acid dihydrate maʻemaʻe kiʻekiʻe (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) me ka kaohi maikaʻi. ʻO kā mākou waikawa oxalic papa ʻoihana e haʻaheo nei i ka maʻemaʻe liʻiliʻi o 99.6%, e ʻike ʻia ana he pauka crystalline keʻokeʻo me nā pae haumia haʻahaʻa (sulfate ≤0.1%, metala kaumaha ≤0.002%, hao ≤0.003%). Hoʻohana nui ʻia ia i ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka lole, ka hana ʻili, ka hoʻomaʻemaʻe ʻana i ka ʻili metala, ka poli ʻana i ka marble, ka mālama ʻana i ka wai, ka unuhi ʻana i ka honua laha ʻole, a me ka synthesis waena o nā lāʻau lapaʻau.
Mālama mākou i ka waihona nui ma kā mākou hale kūʻai ma Shandong, e hiki ai ke hoʻouna koke ʻia no nā kauoha nui. ʻO nā koho hoʻopili maʻalahi (25kg, 50kg, 1000kg mau ʻeke) a me ka hoʻouna ʻana i ke ao holoʻokoʻa mai nā awa ʻo Qingdao, Tianjin, a i ʻole Shanghai e hōʻoia i ka lawe ʻana i ka manawa kūpono ma ka honua holoʻokoʻa. Hāʻawi mākou i ke kākoʻo loea piha, nā palapala COA/MSDS, a me nā kumukūʻai hoʻokūkū e hoʻokō i nā pono ʻoihana like ʻole.
E kāhea mai iā mākou i kēia lā no kahi ʻōlelo kikoʻī maʻamau a hoʻopaʻa i kāu kaulahao hoʻolako waikawa oxalic.
