Propionic Acid National Standard (GB Specifications)
Cik mi ng'om pi propionic acid nyutho maleng kite ma enen kudu: ecibedo piny ma rangi pare epe, ma leng ku nguc ma ngic, man rangi pare umaku urombo ku cik mi rangi (e.g., ku wel pa APHA ma kadhu ngo wel ma juketho) mi neno nia piny ne urombo ku kite ma enen kudu.
I lembe mi leng pa piny, cik mi ng'om ukwayu nia juyik propionic acid ma romo 99.0%. Piny ma pire tek eni mitere nia propionic acid timo tic maber man ma gen ikind tic matung tung mi yubu piny man tic kudu. Piny ma pii pii utiye piny mapire tek ma loko ber pa piny; nimakere ku cik, pii ucikere ni bedu piny pa 0.5% mi gwoko pii madwong kud unyoth kite pa kemikol man tic pare. Acidity, calu lanyuth ma pire tek, de jukoro maleng: acidity (junyutho calu mass fraction, maju kwanu calu propionic acid) umaku ubed i kind rwom ma juketho pi ketho kero pa piny ma juyubu man tic pare urombo ku yeny. Piny ma pek utiye piny ma juketho i cik—lead, mercury, man piny mange ma pek juketho i rwom ma piny akeca, ma jupimu i ppm (parts per million), mi bedo ber pi tic kudu i cam, yath, man tic mange ma pire tek.
Cik mi ngom bende ketho cik ma cuu ikum pek pa dhanu. I lyethu moko (e.g., 20°C), pek pa piny ucikere ni bedu i kind piny moko, ma nyutho ka piny ma juyubu kudu urombo ku cik. Kabedo mi lyethu ubedo lembe mange ma pire tek: propionic acid umaku obed ku rwom mi lyethu ma romo 140°C – 142°C, mi neno nia lyethu man kero pare urombo ku yeny mi tic. Kite ma chloride utiye kudu juyike matek, ku cik ma kwayu nia chloride ubed piny pa rwom moko (e.g., 0.001%) pi jwigo adwogi marac ikum ber pa piny man tic ma lubo. Kite ma iron utiye kudu de utiye ku rwom ma yot, ma kadhu 0.0001%, mi jwigo iron elements ma nyayu peko i rangi, bedo moth, man tic pa propionic acid i tic moko ma pire tek.
I kum lembe mi nyai, cik mi ng'om mito ni propionic acid unyutho nyai maber i jamb tiyo moko (calu, ethanol, diethyl ether), ma weko bedo maber i ratios moko ni rombu ku yeny mi yubu piny i yore matung tung mi tic.
