Ke nānā nei i ka mōʻaukala hoʻomohalaʻana o kaʻoihana polyester, hiki iā mākou ke loaʻa ma mua o ka 90% o nā mea kanu polyester e hoʻohana ai i nā mea kanu. E 2000, ua hōʻikeʻo Kina i nā mea kanu he nui, nā mea āpau i hoʻohanaʻia e nā catalysts, nui loa sb2o3 a me sb (cb3coo) 3. Ma o nā hana hoʻokūkū o nā mea noiʻi o Kina, nā kulanui, a me nā keʻena hana, ua hana pihaʻia kēia mau hale kūʻaiʻelua.
Mai ka makahiki 1999, ua hanaʻo French Chinese Company Chinese Elf i kahi Glycol antimino [SB2 (OCH2CH2CO) 3] Catalyst ʻO nā pahu polyester i hanaʻia he keʻokeʻo kiʻekiʻe a me ke kiʻi maikaʻi, ua hoihoi i nā hana noiʻi waiwai mai ka hale noiʻi pūnaewele ma Kina.
I. noiʻi a me ka noiʻana o keʻano o ka animony trioxide
ʻO ka United States kekahi o nā'āina mua e hana a noi iā SB2O3. I ka makahiki 1961, ka hoʻopauʻana o Sb2O3 maʻAmelika Hui PūʻIa i hōʻea 4,943 TENs. I nā makahiki 1970,ʻelima mau hui ma Iapana i hana i Iapana sb2O3 me kahi hiki i ka nui o ka hana o 6,360 Tons i hoʻokahi makahiki.
Ua nānā nuiʻiaʻo Kina SB2O3 noiʻi a me nā hana hoʻomohala hoʻomohala nui i nāʻoihana aupuni i loko o Hunan. Urbanmines Tech. Hoʻopaʻa hou pū kekahi i hoʻokumu i kahi laina hana lapaʻau ma Human Country.
(I). Ke ala no ka hanaʻana i ka triomide antimide
Hoʻohana ka hana o SB2O3 maʻamau i ka hana antimony sulfide sulfide ot e like me ka meaʻala. Ua mākaukauʻo Aledimy i mākaukau mua, a laila ua hanaʻiaʻo SB2O3 e hoʻohana ana i ka maleʻana me keʻano o keʻano o keʻano.
Aia heʻelua mau ala nui no ka hanaʻana i ka sb2O3 mai keʻano metallic antimony
1.
ʻO nā hopena antimuny nā hopena me ka oxygen ma lalo o ka hoʻomehanaʻana e hana ana i ka sb2O3. ʻO ke kaʻina hana penei:
4sb + 3o2 == 2sb2O3
2. Jobyissis
Ua hoʻohālikelikeʻiaʻo Antimony i ka chlorine e synthesize antimenthesize antimen, i hanaʻia, hydown, a maloʻo hoʻi e loaʻa ai ka huahana. ʻO ka hoʻohālikelike kumu maʻamau:
2sb + 3cl2 == 2sbl3
Sbcl3 + H2O == Sboll + 2hcl
4sbial + hnoo === Sb2O3 · 2SBOL + 2hcL
Sb2ole3 · 2SBocl + Oh == 2sb2o3 + 2nh4Cl32 .2
(II). Hoʻohanaʻana i nā triomidentide
ʻO ka hoʻohana nuiʻana o keʻano he trioxide e like me kahi catalyst no ka polyherse a me kahi retadant flame no nā mea hana synthetic.
I kaʻoihana polyester, ua hoʻohana muaʻiaʻo SB2O3 ma keʻano he catalyst. Ua hoʻohana nuiʻiaʻo SB2O3 e like me ka mea polycondentation canalyst no ka ala DMT a me ke alaʻo PTA ala a me kāna mau enzymes.
(III). ʻO nā pilikia me nā trioxide antimony
Sb2O3 i loaʻa i ka maluhia maikaʻi loa ma Ethylene Glycol, me kahi pālolo o ka 4.04% ma 150 ° C. No laila, i ka manawa i hoʻohanaʻia aiʻo 'olokama Glycol e hoʻomākaukau i ka catalyst, kahi e hiki ai ke kīwīwīwīwīwī ma mua. E hoʻomaikaʻi i ka pālolo a me kaʻaeʻole o sb2O3 ma Ethlynene Glycol, ua hana pinepineʻia e hoʻohana i keʻano o keʻano o keʻano he 120 ° c. Eia nō naʻe, ma luna o 120 ° C, Sb2O3 a me Ethylene Glycol i ka manawa lōʻihi a pili i ka maikaʻi o ka polycoech.
II. ʻO ka noiʻi a me ka noiʻana o ka Ancomony Actetate
ʻO keʻano hoʻomākaukauʻana o ka maʻi antimony
I ka wā mua, ua hoʻomākaukauʻia ka maʻi antimony e hana ana i ka hana antimony trixide me ka acetic acetic e like me ka wai i hanaʻia e ka hopena. ʻAʻole i kiʻekiʻe ka maikaʻi o ka huahana i loaʻa e kēiaʻano, a ua alakaʻiʻia mua i nā kaʻa alimy e hoʻopiʻiʻia i ka aila. Ma hope iho, ua mākaukau encsion hoʻohuiʻia e keʻanoʻana i ka anmeimelea, Antimony Trichyide,ʻaʻohe mea e pono ai ka animalogy, me ka pono no ka hana dehytracedi.
1. Ancony Trichloride
I ka makahiki 1947, H. Schmidt et al. ma West Germany i hoʻomākaukauʻiaʻo SB (Ch3coo) 3 ma ka hoʻohuliʻana iā SBCL3 me Actetic Anyddride. ʻO kaʻanoʻanoʻano penei:
Sbcl3 + 3 (Ch3co) 2o == sb (ch3coo) 3 + 3ch3cocl
2
I ka makahiki 1954, Tapaybea o ka mea hoʻohana o Soviet i hoʻomākaukauʻiaʻo Sb (Ch3coo) 3 ma ka hanaʻana i keʻano metallic a me ka peroynecyl. ʻO keʻanoʻanoʻano.
SB + (Ch3coo) 2 == SB (Ch3coo) 3
3
I ka makahiki 1957, F. Nerdel o West Germany i hoʻohanaʻia i Sb2O3 e hana me ka ACTIC ACTIC (CH3coO) 3.
Sb2o3 + 3 (sh3co) 2o == 2sb (ch3coo) 3
ʻO ka hemahema o kēia ala keʻano o nā crystals e hoʻonāukiuki i nā'āpana nui a me nā lāʻau i hoʻopaʻaʻia i ka pā o ka mea hana i loko
4.ʻO Antimey tooxide solvent
E lanakila i nā pōkole o keʻano o luna,ʻo kahi mea hana maʻamau e hoʻohui pinepineʻia i ka hopena o ka hopena o SB2O3 a me ACTIC ACTOCRIDIID. ʻO keʻano hoʻomākaukau kūikawā e like me kēia:
(1) I ka makahiki 1968, R. Thoms o kaʻAmelika Hui PūʻIa i paʻiʻia i kahi papa hana ma ka hoʻomākaukauʻana o keʻano o ka hoʻomākaukauʻana. Ua hoʻohanaʻia ka mea hana Xylene (O-, M-, P-xylene, a iʻole kahiʻano hoʻohālikelike o nā crystals maikaʻi loa.
(2) i ka makahiki 1973, ua hana ka Repubalika Czech Republic i kahi ala no ka hanaʻana i ka maʻi antimony maikaʻi e hoʻohana ana i ka toluene e like me ka selvent.
