Xiyimo xa Rixaka xa Propionic Acid (Swihlawulekisi swa GB) .
Mpimo wa rixaka wa propionic acid wu hlamusela kahle xivumbeko xa yona: wufanele kuva mati lawa yangariki na muhlovo, lawa ya vonakaka lawa yanga na nun’hwelo wo bava, naswona muhlovo wa wona wufanele ku fikelela swipimelo swokarhi swa visual colorimetric (xikombiso, na nhlayo ya APHA leyinga hundzi mpimo lowu vekiweke) ku tiyisisa leswaku xiendliwa xi fikelela swilaveko swa khwalithi ya xivumbeko.
Hi mayelana na ku basa, mpimanyeto wa tiko wu lerisa nhlayo yale hansi ya propionic acid ya 99.0%. Xilaveko lexi xa vutengi byale henhla xitiyisisa leswaku propionic acid yi tisa matirhelo yo tiya no tshembheka eka swiyimo swohambana hambana swa vuhumelerisi bya ti indasitiri na matirhiselo. Nhlayo ya ndzhongho i nchumu wa nkoka swinene lowu khumbhaka khwalithi ya swihumelerisiwa; hi standard, mati yafanele ku lawuriwa ehansi ka 0.5% ku sivela kutsakama loku tlulaka mpimo kuva ku kavanyeti swivumbeko swa yona swa ti khemikhali xikan’we na matirhelo. Acidity, tani hi xikombiso xa nkoka, yitlhela yi boxiwile kahle: acidity (leyi kombisiwaka tani hi mass fraction, leyi hlayiwaka tani hi propionic acid) yifanele ku wela eka ndzhawu leyi hlamuseriweke ku tiyisisa ku tiya ka ti khemikhali ta xiendliwa xikan’we na reactivity ya fikelela swilaveko. Nhlayo ya tinsimbi to tika yi pimiwile swinene eka mpimanyeto—ntsopfu, mercury na tinsimbi tin’wana to tika ti pimiwile eka mpimo wa le hansi swinene, hi ntolovelo wu pimiwa hi ppm (swiphemu hi miliyoni), ku tiyisisa vuhlayiseki ku tirhisiwa eka swakudya, mirhi na tiindasitiri tin’wana leti nga na vuxiyaxiya.
Mpimo wa tiko wutlhela wu veka swilaveko leswi kongomeke eka density. Eka mahiselo lawa ya vekiweke (xikombiso, 20°C), density yifanele kuwela eka ndzhawu leyi hlamuseriweke, leswi kombisaka loko swivumbeko swa physical swa xiendliwa swilandzela swipimelo. Ndzhawu yo vila i yin’wana ya nkoka leyi faneleke ku tekeriwa enhlokweni: propionic acid yifanele kuva na ndzhawu yo vila hi xitalo 140°C – 142°C, kutiyisisa leswaku kutshamiseka ka yona eka mahiselo xikan’we naku cinca cinca swifikelela swilaveko swa ti indasitiri leswi fambelanaka. Nhlayo ya chloride yi lawuriwa swinene, laha standard yi lavaka leswaku ti levele ta chloride tiva ehansi ka threshold yokarhi (xikombiso, 0.001%) ku sivela ku khumbeka ko biha eka khwalithi ya swihumelerisiwa xikan’we naku lulamisiwa loku landzelaka. Nhlayo ya iron yitlhela yiva ehansi ka swipimelo leswinga erivaleni, hi ntolovelo ayi hundzi 0.0001%, ku papalata ti iron elements leti khumbhaka muhlovo, kutshamiseka, na matirhelo ya propionic acid eka switirhisiwa swokarhi swo hlawuleka.
Malunghana na ku n’oka, mpimanyeto wa rixaka wu lava leswaku propionic acid yi kombisa ku n’oka lokunene eka swintshuxo swo karhi (xikombiso, ethanol, diethyl ether), leswi pfumelelaka ku hlangana loku heleleke eka ti ratio to karhi ku fikelela swilaveko swa ku endliwa eka swiyimo swo hambana swa ku tirhisiwa.

Shandong Pulisi Chemical Co., Ltd. i muendli wo hlawuleka na muphakeri wa xiyimo xa le henhla xa indasitiri-giredi ya propionic acid eChina, loyi a tinyiketeleke ku tisa ku basa loku nga cincekiki, mphakelo lowu tshembekaka, na swintshuxo leswi lulamisiweke eka tiklayenti ta tiindasitiri ta misava hinkwayo. Propionic acid ya hina yi humelerisiwa ehansi ka swipimelo swo tika swa GB/T 10615, laha ku basa ka giredi ya premium kufikaka eka ≥99.5% na giredi yosungula eka ≥99.0%, leyi kombisaka ndzhongho wale hansi, nhlayo yale hansi ya ayoni, na ti levele ta nsimbi yo tika leti lawuriwaka ku fikelela swilaveko leswi lavaka swa switirhisiwa swohambana hambana swa matirhiselo yo hetelela.
Yi endliwe hiku tirhisa thekinoloji ya xiyimo xale henhla ya propylene oxidation, propionic acid ya hina yitiyisisa swivumbeko swa tikhemikhali leswi tiyeke, ku n’oka lokunene, na khwalithi leyi nga cincekiki batch endzhaku ka batch. Yitirha tani hi xitirhisiwa xa nkoka eka organic synthesis, vumaki bya tipulasitiki, maendlelo ya electroplating, nhlayiso wa swakudya na swakudya, na vuhumelerisi bya mirhi na agrochemical. Hi seketeriwa hi laboratori ya hina ya vulawuri bya khwalithi ya le ndzeni na tiphrothokholi to kambela leti heleleke, ku rhumeriwa kun’wana na kun’wana ku fambisana na COA leyi heleleke, MSDS, na matsalwa man’wana ya ku landzelela ku olovisa ku nghenisiwa na ku tirhisiwa lokunene emisaveni hinkwayo.
Hi ku tlula malembe ya ntokoto wo rhumela ematikweni mambe eAsia, Yuropa, Middle East, na le handle, hi nyika tindlela to paka leti cinca-cincaka, minxavo yo phikizana, na swipimelo swo tshembheka swa ku rhumela ku katsa na FOB, CIF, na DDP. Kunga khathariseki leswaku u lava tioda letintsongo to ringeta kumbe mphakelo wa xikalo lexikulu, ntlawa wa hina lowu tinyiketeleke wu lulamerile ku nyika nseketelo wa xithekiniki lowu hlamulaka na vukorhokeri lebyi endleriweke ku fikelela swilaveko swa wena swo hlawuleka swa bindzu.
