ʻAno Hoʻopili ʻana o ka Carbon Monoxide Acid Oxalic
I ka wā mua, ua hoʻohana kēia ʻano hana i ka palladium a me nā paʻakai keleawe ma ke ʻano he mau mea hoʻoulu, a ua hoʻokō i kahi hopena hoʻopili wai-pae o ke kalapona monoxide, oxygen, waiʻona, a me ka waikawa nitric dilute ma 8-11 MPa a me 90-100 °C. Hoʻopuka mua ka hopena i ka oxalate ester, a laila hydrolyzed ma lalo o nā kūlana hoʻomehana e hana i ka waikawa oxalic a me ka waiʻona like.
Loaʻa i kēia ʻano hana kahi ʻōnaehana catalyst hoʻokahi, hana kiʻekiʻe, koho maikaʻi, hoʻōla maʻalahi, maʻemaʻe huahana kiʻekiʻe, a me ka haumia hana haʻahaʻa. Eia nō naʻe, he kiʻekiʻe nā koi no ka maʻemaʻe o ke kalapona monoxide, hoʻohana nui, nā catalysts pipiʻi, a me ka hoʻopukapuka kālā kiʻekiʻe.
Me ka hoʻohana ʻana i ka Pd/C ma ke ʻano he mea hoʻoulu, ua hoʻopili ʻia ke kalapona monoxide a me ka nitrite ester e synthesize i ka oxalate ester ma 130 °C a me ke kaomi lewa, me ka nitric oxide ma ke ʻano he huahana ʻaoʻao. Loaʻa ka waikawa Oxalic a me ka waiʻona e pili ana ma ka hydrolyzing ʻana i ka oxalate ester. Hoʻohou hou ʻia ka hopena waiʻona i hoʻokaʻawale ʻia e hana i ka nitrite ester, hiki ke hana hou ʻia.
Ua hana ka Fujian Institute of Structure of Matter, Chinese Academy of Sciences, i kahi noiʻi e pili ana i ka lakio o nā mea maka a me nā kūlana wikiwiki like ʻole o ka lewa ma ka synthesis catalytic o dimethyl oxalate i ka noiʻi ʻana i nā catalysts no ka hoʻopili catalytic kaomi lewa o CO i ka waikawa oxalic, a ua koho i nā kūlana hopena kūpono. Ua loaʻa i ka catalyst Pd (2.0%)/α-Al₂O₃ i hoʻomaikaʻi ʻia kahi hua manawa-lewa o 999 g/L·h ma lalo o nā kūlana o ke kaomi lewa, 140 °C, CO/CH₃ONO=1.5, a me ka wikiwiki o ka lewa o 3000/h. Ua hana pū ka ʻoihana me ka Fujian Petrochemical Design Institute a me Fujian Nanqing Ammonia Plant e hana i kahi hoʻāʻo hoʻāʻo 100 t/a o ka hoʻōla ʻana i ka CO mai ka holoi ʻana i ke keleawe ammonia synthetic, ka synthesis catalytic kaomi lewa o dimethyl oxalate, a me ka hydrolysis i ka waikawa oxalic.
Ke hoʻohālikelike ʻia me ke ʻano hana wai-pae, he kiʻekiʻe ke koho ʻana o kēia ʻano hana, kaʻina hana maʻalahi, ka maʻemaʻe huahana kiʻekiʻe, a me ke kumukūʻai hana haʻahaʻa. Hiki iā ia ke hoʻohana i ke kinoea kūlohelohe a i ʻole ke lanahu ma ke ʻano he mea maka, a hiki nō hoʻi ke hoʻohana i ke kalapona monoxide i hoʻōla ʻia mai ka holoi ʻana i ke keleawe ammonia a i ʻole ka umu phosphorus melemele, ka umu pahū, a me ke kinoea huelo mea hoʻololi ma ke ʻano he kumu kinoea carbon monoxide. I ka manawa like, hiki iā ia ke hāʻawi i nā mea maka haʻahaʻa no ka hana ʻana o ka ethylene glycol a me ka synthesis i hoʻohui ʻia me ka oxalate ester ma ke ʻano he waena.

Shandong Pulisi Chemical Co., Ltd. | Mea Hoʻolako Waikawa Oxalic Premium
Ua hoʻokumu ʻia i ka makahiki 2006, loea ʻo Pulisi Chemical i ka waikawa oxalic maʻemaʻe kiʻekiʻe (CAS 144-62-7) e kūlike ana me nā kūlana hoʻokuʻu aku honua no nā pae ʻoihana a me nā pae i hoʻomaʻemaʻe ʻia. Hōʻoia kā mākou hale hana hana ma Zibo i ka kaohi maikaʻi loa, me ka waikawa oxalic pae ʻoihana e haʻaheo ana i ka liʻiliʻi he 96% maʻemaʻe a me ka pae i hoʻomaʻemaʻe ʻia e hiki ana i ka 99.6% maʻemaʻe—e hoʻokō ana i nā koi ʻoihana like ʻole.
ʻO kā mākou waikawa oxalic e kū nei no kona solubility maikaʻi loa a me nā waiwai kemika paʻa, e lawelawe ana ma ke ʻano he mea maka maʻalahi ma nā ʻāpana like ʻole. I ka hana ʻana i ka metala, wehe pono ia i nā papa ʻōpala a me nā papa oxide o ka ʻili mai ke kila, ka alumini, a me ke keleawe, e hoʻomaikaʻi ana i ka hoʻopili ʻana o ka uhi no nā kaʻa, aerospace, a me nā noi electroplating. I loko o nā lole, hana ia ma ke ʻano he mea hoʻokeʻokeʻo eco-friendly a me ka dye fixative, e hoʻomaikaʻi ana i ka paʻa o ke kala o ka lole a me ka ʻōlinolino.
Eia kekahi, hoʻohana nui ʻia ia i ka synthesis lāʻau lapaʻau, ka hana ʻana i ka lāʻau, ka unuhi ʻana i ka metala honua laha ʻole, a me ka mālama ʻana i ka unahi wai. Hōʻoia ʻia me ISO 9001 a me EU REACH, hāʻawi mākou i ka ʻōpala 25kg maʻamau no nā kauoha nui, e hōʻoiaʻiʻo ana i ka lako honua hilinaʻi. Inā no ka hana ʻoihana nui a i ʻole nā ​​​​​​noi kiʻekiʻe, hāʻawi ʻo Pulisi Chemical i ke kūlana kūlike a me ke kākoʻo ʻoihana.
