Umgangatho weSizwe wePropionic Acid (Iinkcukacha zeGB)
Umgangatho wesizwe we-propionic acid uchaza ngokucacileyo imbonakalo yayo: mayibe lulwelo olungenambala, olucacileyo olunevumba elibi, kwaye umbala wayo kufuneka uhlangabezane nemigangatho ethile ebonakalayo yombala (umz., enexabiso le-APHA elingadluli umda othile) ukuqinisekisa ukuba imveliso iyahlangabezana neemfuno zomgangatho wokubonakala.
Ngokuphathelele ubunyulu, umgangatho wesizwe uyalela ukuba umxholo we-asidi ye-propionic ube yi-99.0%. Le mfuneko yobunyulu obuphezulu iqinisekisa ukuba i-asidi ye-propionic inika ukusebenza okuzinzileyo nokuthembekileyo kuzo zonke iimeko zemveliso yemizi-mveliso kunye nokusetyenziswa kwayo. Umxholo wobunyulu yinto ebalulekileyo echaphazela umgangatho wemveliso; ngokomgangatho, umxholo wamanzi kufuneka ulawulwe ngaphantsi kwe-0.5% ukuthintela ukufuma okugqithisileyo ekuphazamiseni iipropati zayo zeekhemikhali kunye nokusebenza kwayo. Ubunyulu, njengesalathisi esiphambili, bukwacacisiwe ngokucacileyo: ubunyulu (obuchazwa njengeqhezu lobunzima, obubalwe njenge-asidi ye-propionic) kufuneka bube ngaphakathi koluhlu oluchaziweyo ukuqinisekisa uzinzo lweekhemikhali zemveliso kunye nokusebenza kwayo kuyahlangabezana neemfuno. Umxholo wesinyithi esinzima ulinganiselwe ngokungqongqo kumgangatho—i-lead, i-mercury, kunye nezinye iisinyithi ezinzima zikhawulelwe kumanqanaba aphantsi kakhulu, ahlala elinganiswa kwi-ppm (iindawo ngesigidi), ukuqinisekisa ukhuseleko lokusetyenziswa ekutyeni, kumayeza, nakwamanye amashishini anobuzaza.
Umgangatho wesizwe ukwabeka iimfuno ezichanekileyo kuxinano. Kubushushu obuthile (umz., 20°C), uxinano kufuneka lube ngaphakathi koluhlu oluchaziweyo, nto leyo ebonisa ukuba iimpawu zomzimba zemveliso ziyahambelana nemigangatho. Uluhlu lokubilisa lolunye uqwalaselo oluphambili: i-propionic acid kufuneka ibe noluhlu lokubilisa oluyi-140°C ukuya kwi-142°C ngokubanzi, ukuqinisekisa ukuba uzinzo lwayo lobushushu kunye nokuguquguquka kwayo kuhlangabezana neemfuno zoshishino ezifanelekileyo. Umxholo we-chloride ulawulwa ngokungqongqo, apho umgangatho ufuna amanqanaba e-chloride abe ngaphantsi komlinganiselo othile (umz., 0.001%) ukuthintela impembelelo embi kumgangatho wemveliso kunye nokucutshungulwa okulandelayo. Umxholo we-iron ukwaxhomekeke kwimida ecacileyo, edla ngokungadluli kwi-0.0001%, ukuze kuthintelwe izinto ze-iron ezichaphazela umbala, uzinzo, kunye nokusebenza kwe-propionic acid kwizicelo ezithile ezikhethekileyo.
Ngokuphathelele ukunyibilika, umgangatho wesizwe ufuna i-propionic acid ukuba ibonakalise ukunyibilika okuhle kwizinyibilikisi ezithile (umz., i-ethanol, i-diethyl ether), okuvumela ukuxubeka ngokupheleleyo kwiimilinganiselo ezithile ukuhlangabezana neemfuno zokwenziwa kwiimeko ezahlukeneyo zokusetyenziswa.

I-Shandong Pulisi Chemical Co., Ltd. ngumvelisi okhethekileyo kunye nomthengisi we-propionic acid ekumgangatho ophezulu kwimizi-mveliso eTshayina, ezinikele ekunikezeleni ubunyulu obuhlala buhleli, unikezelo oluthembekileyo, kunye nezisombululo ezenzelwe abathengi bemizi-mveliso kwihlabathi liphela. I-propionic acid yethu iveliswa phantsi kwemigangatho engqongqo ye-GB/T 10615, kunye nobunyulu be-premium grade obufikelela kwi-≥99.5% kunye ne-first grade kwi-≥99.0%, enomswakama ophantsi, umxholo wesinyithi ophantsi, kunye namanqanaba esinyithi alawulwayo ukuhlangabezana neemfuno ezifunekayo zezicelo ezahlukeneyo zokusetyenziswa.
Yenziwe ngetekhnoloji ye-propylene oxidation ephucukileyo, i-propionic acid yethu iqinisekisa iipropati zeekhemikhali ezizinzileyo, ukunyibilika okugqwesileyo, kunye nebhetshi yomgangatho ohambelanayo emva kwenye. Isebenza njengendawo ephambili ekuhlanganisweni kwezinto eziphilayo, ukwenziwa kweplastiki, iinkqubo ze-electroplating, ukugcinwa kokutya kunye nokutya, kunye nemveliso yamayeza kunye ne-agrochemical. Ixhaswa yilabhoratri yethu yokulawula umgangatho kunye neenkqubo zovavanyo ezibanzi, yonke impahla ethunyelwayo ihamba kunye ne-COA epheleleyo, i-MSDS, kunye namanye amaxwebhu okuthobela ukuze kube lula ukungenisa nokusetyenziswa okutyibilikayo kwihlabathi liphela.
