Propionic Acid Omutindo gw’eggwanga (Ebikwata ku GB) .
Omutindo gw’eggwanga ogwa asidi wa propionic gutegeeza bulungi endabika yaayo: gulina okuba amazzi agataliimu langi, agatangaala nga gawunya nnyo, era langi yaago erina okutuukana n’omutindo ogw’enjawulo ogw’okupima langi (okugeza, ng’omuwendo gwa APHA tegusukka kkomo eriragiddwa) okukakasa nti ekintu kituukana n’ebisaanyizo by’omutindo gw’endabika.
Mu nsonga z’obulongoofu, omutindo gw’eggwanga gulagira asidi wa propionic asinga obutono ebitundu 99.0%. Okwetaaga kuno okw’obulongoofu obw’amaanyi kukakasa nti asidi wa propionic atuwa omulimu ogutebenkedde era ogwesigika mu mbeera ez’enjawulo ez’okufulumya n’okukozesa mu makolero. Obunnyogovu nsonga nkulu nnyo ekwata ku mutindo gw’ebintu; okusinziira ku mutindo, amazzi galina okufugibwa wansi wa 0.5% okuziyiza obunnyogovu obuyitiridde okutaataaganya eddagala lyago n’enkola yaago. Asidi, ng’ekiraga ekikulu, era kirambikiddwa bulungi: asidi (eyolesebwa ng’ekitundu ky’obuzito, ebaliriddwa nga asidi wa propionic) erina okugwa mu bbanga eritegeerekese okukakasa nti ekintu ekyo kinywevu mu kemiko n’okuddamu okutuukiriza ebisaanyizo. Ebirimu ebyuma ebizito bikoma nnyo mu mutindo —omusulo, mercury, n’ebyuma ebirala ebizito bikoma ku miwendo gya wansi nnyo, ebiseera ebisinga bipimibwa mu ppm (ebitundu ku buli bukadde), okukakasa obukuumi okukozesebwa mu mmere, eddagala, n’amakolero amalala agakwata ku nsonga.
Omutindo gw’eggwanga era gussaawo ebisaanyizo ebituufu ku density. Ku bbugumu eriragiddwa (okugeza, 20°C), density erina okugwa mu bbanga eritegeerekese, ekiraga oba eby’obutonde eby’ekintu bituukana n’omutindo. Ekifo ky’okufumba kye kintu ekirala ekikulu eky’okulowoozaako: asidi wa propionic alina okuba n’obuwanvu bw’okufumba okutwalira awamu 140°C – 142°C, okukakasa nti obutebenkevu bwayo mu bbugumu n’okukyukakyuka kwayo bituukana n’obwetaavu bw’amakolero obukwatagana. Ebirimu chloride bifugibwa nnyo, nga omutindo gwetaaga emiwendo gya chloride okubeera wansi w’omutindo ogugere (okugeza, 0.001%) okuziyiza okukosebwa okubi ku mutindo gw’ebintu n’okulongoosa okuddirira. Ebirimu ekyuma nabyo biba n’ekkomo eritegeerekeka, mu bujjuvu nga tebisukka 0.0001%, okwewala ebintu by’ekyuma ebikosa langi, okutebenkera, n’enkola ya asidi wa propionic mu nkola ezimu ez’enjawulo.
Ku bikwata ku kusaanuuka, omutindo gw’eggwanga gwetaaga asidi wa propionic okulaga okusaanuuka okulungi mu biwunyiriza ebitongole (okugeza, ethanol, diethyl ether), okusobozesa okutabula okujjuvu ku migerageranyo egimu okutuukiriza ebyetaago by’okukola mu mbeera ez’enjawulo ez’okukozesa.

Shandong Pulisi Chemical Co., Ltd. ye kkampuni ey’enjawulo ekola era egaba asidi wa propionic ow’omutindo ogwa waggulu mu makolero mu China, eyeewaddeyo okutuusa obulongoofu obutakyukakyuka, okugabibwa okwesigika, n’okugonjoola ebizibu ebituukira ddala ku bakasitoma b’amakolero mu nsi yonna. Asidi waffe owa propionic akolebwa wansi w’omutindo omukakali ogwa GB/T 10615, ng’obulongoofu bwa ddaala ery’omutindo ogwa waggulu butuuka ku ≥99.5% ate mu ddaala erisooka ku ≥99.0%, ng’erina obunnyogovu obutono, ekyuma ekitono, n’emiwendo gy’ebyuma ebizito ebifugibwa okusobola okutuukiriza ebyetaago ebisaba eby’okukozesa okw’enjawulo okw’enkomerero.
Ekoleddwa nga tuyita mu tekinologiya ow’omulembe ow’okuziyiza propylene oxidation, asidi waffe ow’ekika kya propionic akakasa eby’obugagga by’eddagala ebinywevu, okusaanuuka okulungi ennyo, n’omutindo ogukwatagana batch oluvannyuma lw’ekibinja. Kikola ng’ekintu ekikulu eky’omu makkati mu kusengejja ebiramu, okukola obuveera, enkola z’okusiiga amasannyalaze, okukuuma emmere n’emmere, n’okukola eddagala n’eddagala ly’ebyobulimi. Nga tuwagirwa laboratory yaffe ey’okulondoola omutindo mu nnyumba n’enkola z’okugezesa enzijuvu, buli mugugu guwerekerwako ebiwandiiko ebijjuvu ebya COA, MSDS, n’ebirala ebigoberera okusobola okwanguyiza okuyingiza n’okukozesa obulungi mu nsi yonna.
Nga tulina obumanyirivu obusukka mu myaka egy’okutunda ebintu mu Asia, Bulaaya, Middle East, n’okusingawo, tuwaayo enkola ezikyukakyuka mu kupakinga, emiwendo egy’okuvuganya, n’ebiragiro ebyesigika eby’okutuusa ebintu omuli FOB, CIF, ne DDP. Ka obe nga weetaaga orders entonotono ez’okugezesa oba ebikozesebwa ebinene mu bungi, ttiimu yaffe eyeewaddeyo yeetegefu okuwa obuyambi obw’ekikugu obuddamu n’empeereza erongooseddwa okusobola okutuukiriza ebyetaago byo eby’enjawulo ebya bizinensi.
