Propionic Acid National Standard (GB Specifications)
Ing pambansang pamantayan para keng propionic acid malino yang magdefine keng itsura na: dapat yang alang kule, transparent a likidu a maki mabangis a bau, at ing kule na dapat makatupad ya kareng specific visual colorimetric standards (alimbawa, ing APHA value na e lalagpus keng metung a limitasyun) para makasiguradung ing produktu makatupad ya kareng requirements ning kalidad ning itsura.
keng purity, ing national standard mandatu yang minimum a propionic acid content a 99.0%. Ing high-purity requirement ayni sisiguradwan na ing propionic acid magdalang matatag ampo mapanalig a performance kareng miyayaliwang industrial production ampo application scenarios. Ing moisture content metung yang kritikal a sangkan na makaapektu keng kalidad ning produktu; agpang keng standard, ing laman ning danum dapat yang makontrol lalam ning 0.5% para aiwasan ing sobrang danum a maka-interfere kareng kayang chemical properties ampo performance. Ing acidity, bilang metung a susi a indicator, malino ya namang makasulat: ing acidity (a mipalabas bilang mass fraction, a makalkula bilang propionic acid) dapat yang milub king metung a makatuldung range para makasiguradung ing chemical stability ampo reactivity ning produktu makatupad ya kareng requirements. Ing heavy metal content limitadu ya keng standard—lead, mercury, ampo reng aliwang heavy metal limitadu la keng sobrang mababang antas, keraklan susukat la keng ppm (parts per million), para siguraduan ing kaligtasan para gamitan keng pamangan, parmasyutika, ampo aliwa pang sensitibong industriya.
Ing pambansang pamantayan mag impose yang eksaktung requirements keng density. keng metung a temperatura (alimbawa, 20°C), ing density dapat miras ya keng metung a range, a magpakit nung ing physical properties ning produktu makayagpang ya kareng standards. Ing boiling range metung yang susi a konsiderasyun: ing propionic acid dapat atin yang boiling range a keraklan 140°C – 142°C, makasiguradung ing kayang thermal stability ampo volatility makatupad ya kareng katumbas a industrial demands. Ing chloride content mahigpit yang regulated, ing standard na kailangan ing chloride levels atyu lalam ning metung a specific threshold (eg, 0.001%) para aiwasan ing e masanting a epektu keng kalidad ning produktu ampo ing kayang pamagprosesu. Ing laman ning bakal atin yang malino limitasyun, keraklan e la lalagpus 0.0001%, para aiwasan ing bakal a makaapektu keng kule, katatagan, ampo performance ning propionic acid kareng mapilan a specialized a aplikasyun.
Patungkul keng solubility, ing national standard mangailangan yang propionic acid para mika masanting a solubility kareng specific solvents (alimbawa, ethanol, diethyl ether), a magpaintulut keng kumpletung miscibility kareng mapilan a ratio para akit ing formulation requirements kareng miyayaliwang senaryo ning aplikasyun.
