Propionic Asid Omutindo gw'eihanga (ebirikushoboororwa GB)
Omutindo gw‘eihanga ogwa propionic acid nigushoboorora gye oku erikureebeka: neija kuba eri amaizi agataine rangi, agarikureebeka gye kandi gaine ekinuuko ky‘amaani, kandi erangi yaayo eine kuhikiiriza emitindo y‘okureeba erangi (nk‘eky‘okureeberaho, n‘omuhendo gwa APHA ogutarikurenga aha kikomo ekimanyirwe) kureeba ngu ekintu kyahikiiriza ebyetaago by‘omutindo gw‘okureebeka.
Aha bikwatiraine n’obuyonjo, omutindo gw’eihanga niguragiira ngu ebiriisa bya propionic acid bibe biri ahansi ya 99.0%. Ekyetengo eki eky‘obuyonjo bw‘ahaiguru nikihamya ngu propionic acid neereetaho okukora okuhamire kandi okwesigwa omu miringo etari emwe n‘emwe y‘okukora n‘okukoresa eby‘amakorero. Obutagatsi oburimu n’ekintu kikuru ekirikuteganisa omutindo gw’ebintu; aha mutindo, amaizi gaine kukyeberwa ahansi ya 0.5% okuzibira obutagatsi oburengire kuteganisa emitwarize yaayo ey’eby’obuhangwa n’okukora kwayo. Asidi, nk‘eky‘okureeberaho kikuru, nayo neeshoboororwa gye: asidi (erikworekwa nk‘ekicweka ky‘oburemeezi, erikubarwa nka asidi ya propionic) eine kugwa omu nkora eshobooroirwe kuhamya okuguma kw‘eby‘obuhangwa n‘okugarukamu kw‘ekintu nibihikiiriza ebirikwetengyesa. Ebyoma ebiremeire ebirimu nibikyeenwa munonga omu mutindo—lead, mercury, n’ebindi byoma ebiremeire nibikyendeezibwa aha rurengo rwahansi munonga, okukira munonga nibipimirwa omu ppm (ebicweka ahari buri miriyoni), kureeba ngu biine oburinzi bw’okubikoresa omu by’okurya, omu by’emibazi, n’omu makorero agandi agarikuteganisa.
Omutindo gw’eihanga nagwo nigutaho ebyetaago ebihikire aha buhango bw’ebintu. Aha bwire bw‘obwire obumanyirwe (nk‘eky‘okureeberaho, 20°C), oburemeezi bw‘okugwa omu nkora obumanyirwe, ekirikworeka yaaba ebiri omu mubiri gw‘ekintu nibihikaana n‘omutindo. Omubaro gw’okufuka n’ekindi kikuru eki oine kuteekateekaho: propionic acid eine kuba eine omubaro gw’okufuka omu bwijwire 140°C – 142°C, kuhamya ngu okuguma kwayo omu bwire bw’okwotsya n’okuhindukahinduka nibihikiiriza ebyetengo by’amakorero ebirikuhikaana. Ebirimu kloride nibiteebwaho ebiragiro bigumire, n‘omutindo ogurikwetengyesa ngu emihendo ya kloride ebe ahansi y‘omutindo ogumanyirwe (nk‘eky‘okureeberaho, 0.001%) okuzibira okukwatwaho kubi aha mutindo gw‘ebintu n‘okukora ebirikukurataho. Ekyoma ekirimu nakyo nikiba kiine obugarukiro oburikworeka gye, omu muringo gw’omutaano obutarikurenga 0.0001%, okwetantara ebintu by’ekyoma ebirikuteganisa erangi, okuhama, n’okukora kwa propionic acid omu mirimo emwe ey’omutaano.
Aha bikwatiraine n‘okushohoza, omutindo gw‘eihanga nigwetengyesa propionic acid kworeka okushohoza kurungi omu bishaju ebimwe (nk‘eky‘okureeberaho, ethanol, diethyl ether), ekirikubaasisa okushohoza okuhikire aha mibaro emwe kuhikiiriza ebyetaago by‘okukora omu mbeera z‘okukoresa zitari zimwe na zimwe.

Shandong Pulisi Chemical Co., Ltd. n’ekitongore ky’omutaano ekirikukora kandi ekirikugaba propionic acid ey’omutindo gw’ahaiguru ey’amakorero omuri China, eyehaireyo kureetaho obushemeire obutarikuhinduka, okuha ebirikwesigwa, n’okugaba eby’okugarukamu ebihikire ahabw’abaguzi b’amakorero omu nsi yoona. Propionic acid yaitu neekorwa ahansi y’omutindo gwa GB/T 10615 ogugumire, n’obushemeire bw’omutindo gw’ahaiguru oburikuhika ≥99.5% n’omutindo gw’okubanza ahari ≥99.0%, erimu obutagatsi bukye, eby’ekyoma bikye, n’ebyoma ebigumire ebirikutegyekwa kuhikiiriza ebyetaago by’okukoresa ebitari bimwe na bimwe.
Ekozirwe kurabira omu tekinologiya y’omurembe eya propylene oxidation, propionic acid yaitu neehamya ngu erimu emibazi egumire, okushohozibwa kurungi, n’omutindo ogutarikuhinduka omu bicweka bwanyima y’ebicweka. Nikikora nk’ekintu kikuru eky’omugati omu kuhanga eby’obuhangwa, okukora obuveera, emiringo y’okukoresa amashanyarazi, okurinda eby’okurya n’eby’okurya, n’okukora emibazi n’eby’obuhingi n’oburiisa. Okushagikwa laboratory yaitu ey’omunda ey’okurinda omutindo n’ebiragiro by’okukyebera ebihikire, buri kimwe ekirikutwarwa omu meeri nikihererukayo COA yoona, MSDS, n’ebihandiiko ebindi ebirikukuratira ebiragiro kuhwera omu kureeta ebintu omu ihanga n’okubikozesa gye omu nsi yoona.
Ahabw’okugira ngu twine emyaka mingi y’okushohoza ebintu aheeru y’ihanga omuri Asia, Europe, Middle East, n’aheeru yaayo, nituha emiringo y’okubiteeka omu bipapura ebirikuhindukahinduka, emihendo y’okuhakanisa, n’ebiragiro by’okubireeta ebirikwesigwa otwariiremu FOB, CIF, na DDP. Yaaba nooyenda ebiragiro bikye by’okugyezesa nari eby’okukoresa bingi, tiimu yaitu eyehaireyo eyeteekateekire kukuha obuhwezi bw’eby’obuhangwa oburikugarukamu n’obuheereza obuhikire kuhikiiriza ebyetengo byawe eby’omutaano eby’obushuubuzi.
