Propionic Acid National Standard (GB chungchang sawifiahna) 1.1.
Propionic acid atana national standard chuan a hmel chu chiang takin a tarlang a: a rawng nei lo, transparent liquid, rimtui tak a ni tur a ni a, a rawng hian visual colorimetric standard bik (eg, APHA value chu a bituk aia tam lo) a tlin tur a ni a, chu chuan product chu a hmel quality mamawh a tlin theih nan a ni.
Thianghlimna lam hawi chuan national standard chuan propionic acid awm zat tlem ber 99.0% a nih tur thu a sawi. He high-purity requirement hian propionic acid hian industrial production leh application scenario hrang hrangah performance nghet leh rintlak a pe thei a ni. Moisture content hi product quality tichhe theitu pawimawh tak a ni a; standard angin, tui awm zat chu 0.5% hnuai lam control a ngai a, chu chuan a chemical property leh performance a tihbuai loh nan moisture tam lutuk chuan a tibuai lo ang. Acidity, key indicator angin, chiang takin tarlan a ni bawk: acidity (mass fraction anga tarlan, propionic acid anga chhut) chu product-a chemical stability leh reactivity-in mamawh a tlin theih nan range ruat saah a tla tur a ni. Heavy metal awm zat hi standard-ah hian khap tlat a ni—lead, mercury, leh heavy metal dangte chu ei leh in, damdawi siamna, leh industry sensitive dangtea hman a him theih nan a level hniam hle a, a tlangpuiin ppm (parts per million)-a teh a ni.
National standard hian density chungchangah pawh thil tul chiang tak a siam bawk. Temperature ruat (eg, 20°C)-ah chuan density chu range ruat sa chhungah a tla tur a ni a, hei hian product-a physical property-te chu standard a zawm leh zawm loh a lantir a ni. Boiling range hi ngaihtuah tur pawimawh dang a ni: propionic acid hian a tlangpuiin 140°C – 142°C vel a boiling range a nei tur a ni a, chu chuan a thermal stability leh volatility chu industrial demands inmil a phuhruk theih nan a pui ang. Chloride awm zat hi khauh taka tihfel a ni a, standard chuan chloride level chu threshold bik (eg, 0.001%) hnuai lam a nih a ngai a, hei hi product quality leh a hnu lama processing-a nghawng tha lo a neih loh nan a ni. Iron awm zat pawh hi limit chiang tak siam a ni a, a tlangpuiin 0.0001% aia tam lo a ni a, hei hi specialized application thenkhata propionic acid rawng, stability leh performance tichhe thei iron elements awm loh nan.
Solubility chungchangah chuan national standard chuan propionic acid hian solvent bik (eg, ethanol, diethyl ether)-ah solubility tha tak a lantir a ngai a, hei hian application scenario hrang hranga formulation mamawh phuhruk turin ratio thenkhatah complete miscibility a phalsak a ni.
