Propionic Acid National Standard (GB Specifications)
Izyeelelo zyacisi zya propionic acid zipandulula kabotu-kabotu mboiboneka: yeelede kuba maanzi aatakwe mubala, aasalala aajisi tununkilizyo tupati, alimwi mubala wayo weelede kuzuzikizya zyeelelo zyakulanga (nkokuti, a APHA value iitaindi aawo mpaabede) kuchitila kuti chintu chili kabotu.
Kweelana akusalala, zyeelelo zyacisi zilaamba kuti asidi ya propionic yeelede kusika ku 99.0%. Eechi chiyandisyo chakusalala loko chisinizya kuti asidi ya propionic ichita obotu akusyomeka mumasena aasiyene-siyene aakupanga akubelesya. Buteteete nchintu chipati loko chijatikizya bubotu bwachintu; kweendelanya amulawu, bunji bwamaanzi bweelede kweendelezyegwa munsi a 0.5% kuchitila kutabilila busi bunji butanyonganyi bube bwamakemikalu akubeleka kwawo. Asidi, mbuli chitondezyo chipati, akwalo kwaambwa antangalala: asidi (itondezyedwe mbuli chibeela chabulemu, ibabalilwa mbuli asidi ya propionic) yeelede kusika mukati kachiimo chibikkidwe kuchitila kuti chipangwa chikkalikene akuchita zintu kweendelana aziyandikana. Bunji bwazibulo zilemu zilabikkwa muchiimo cheelede—lead, mercury, azimwi zintu zilemu zilalesyegwa kusika aansi loko, kanjikanji zipimwa mu ppm (zibeela muli miliyoni), kuchitila kuti zibelesyegwe kabotu muzyakulya, misamu, azimwi zintu zikatazya.
Izyeelelo zyacisi azyalo zibikkila ziyandikana aatala akuvwula kwabantu. Aawo achiindi chakupya (nkokuti, 20°C), bunji bweelede kusika mukati kachiimo chibikkidwe, kutondezya naa bube bwachintu buli kweendelana azyeelelo. Kubila nchintu achimwi chiyandikana: asidi ya propionic yeelede kuba achiindi chakubila cha 140°C – 142°C, kuchitila kuti kutabi kupya akuzungaana kweendelanya aziyandikana mumafakitali. Bunji bwa chloride buli mulawu uusimide, aawo zyeelelo zya chloride zyeelede kuba munsi aachiimo chibikkidwe (nkokuti, 0.001%) kuchitila kutabilila ntenda kububotu bwachintu akuchita zintu zitobela. Bunji bwabutale bulakonzya kubikkwa minyinza iimvwika, kanjikanji butayindi a 0.0001%, kuchitila kutabilila butale butanyonganyi mubala, kukkalikana, akubeleka kwa asidi ya propionic mumilimo imwi.
Kujatikizya kunyoneka, zyeelelo zyacisi ziyanda kuti asidi ya propionic itondezye kunyonyooka kubotu muzintu zimwi zinyonyoona (nkokuti, ethanol, diethyl ether), ikuzumizya kusanganya koonse mumisela imwi kutegwa izuzikizye ziyandikana zyakupanga mumasena aasiyene-siyene.

Shandong Pulisi Chemical Co., Ltd. ngusikupanga akusambala asidi ya propionic iili kabotu loko muChina, uulyaabide kuleta busalali butazungaani, busambazi busyomeka, anzila zigwasya basikuula banyika yoonse. Asidi yesu ya propionic ilapangwa aansi aazyeelelo ziyumu zya GB/T 10615, abulondo bwakusaanguna busika ku ≥99.5% antoomwe abulemu bwakusaanguna busika ku ≥99.0%, kajisi busi busyoonto, butale busyoonto, antoomwe abulemu bupati bwakubelesya zintu zyiingi.
Yakapangwa kwiinda mukubelesya nzila yakusumpula propylene oxidation, asidi yesu ya propionic ilasinizya kuti ilijisi zintu zitazungaani, ilakonzya kunywika kabotu, alimwi ilaa bubotu butazungaani. Chibeleka mbuli chintu chipati akati-akati mukupanga zintu zipona, kupanga mapulasitiki, nzila zyakubelesya magesi, kubamba zyakulya azyakulya, akupanga misamu azyabulimi. Kakugwasyilizyigwa a laboratory yesu iilanganya bubotu bwazintu antoomwe anzila zyakusunka zizulide, zyoonse zituminwa zilatobelwa a COA, MSDS, amapepa aambi aatobela milawu kuchitila kuti kube kuleta kabotu akubelesya munyika yoonse.
Katujisi luzibo lwakutola zintu kuEzhiya, Yulopu, Middle East, akuziindi zyiingi, tulapa nzila zyakupaka zitazungaani, muulo uukonzya kuzundana, anzila zyakutola zisyomeka zibikkilizya FOB, CIF, antoomwe a DDP. Nikuba kuti uyanda maoda masyoonto aakusola naakuti zintu zyiingi, kabunga kesu kalilibambilide kukugwasya alugwasyo lwamilimu yako.
