Njira Yoyezera Propionic Acid
Konzani magalasi monga freette ndi botolo la conical. Potengera kutsimikiza kwa kuchuluka kwa propionic acid muzinthu zamafakitale za propionic acid monga chitsanzo, yesani molondola kulemera kwina kwa chitsanzo cha propionic acid ndikuchiyika mu botolo la conical. Onjezani kuchuluka koyenera kwa madzi osungunuka kuti musungunule chitsanzocho kwathunthu. Kenako sankhani chizindikiro choyenera, monga phenolphthalein. Titrate ndi yankho lokhazikika la sodium hydroxide lomwe lili ndi kuchuluka kodziwika. Pa nthawi ya titration, zimachitika kuti sodium hydroxide ndi propionic acid zisinthe. Pamene sodium hydroxide ikuwonjezedwa, pH ya yankho imawonjezeka pang'onopang'ono. Mapeto a titration amafikiridwa pamene mtundu wa yankho umasintha kuchoka pa mtundu wopanda mtundu kupita ku wofiira wopepuka ndipo umakhala wosasinthika kwa mphindi imodzi. Kutengera kuchuluka kwa yankho lokhazikika la sodium hydroxide lomwe lagwiritsidwa ntchito, kuchuluka kwa propionic acid mu chitsanzocho kumatha kuwerengedwa pogwiritsa ntchito ubale wa stoichiometric. Fomula yeniyeniyo imachokera ku equation ya mankhwala yolinganizidwa ya momwe propionic acid ndi sodium hydroxide zimachitikira, yomwe ili ndi chiŵerengero cha stoichiometric cha 1:1, chosinthidwa pogwiritsa ntchito kuchuluka kwa molar ndi ma formula a mass.info@pulisichem.cn

Shandong Pulisi Chemical Co., Ltd. Chiyambi Chapadera cha Propionic Acid
Shandong Pulisi Chemical Co., Ltd. imagwira ntchito yopereka ndi kugawa Propionic Acid ya mafakitale ndi chakudya chamagulu CAS 79-09-4. Pogwiritsa ntchito njira zowunikira zopanga komanso njira zowunikira zinthu zopangira, propionic acid yathu imakhala ndi chiyero chapamwamba, kuchuluka kochepa kwa zodetsa komanso zinthu zokhazikika zakuthupi ndi zamakemikolo, mogwirizana ndi zofunikira zapadziko lonse lapansi zamakampani ndi chakudya.
Pogwiritsidwa ntchito kwambiri popewa matenda a mildew, kusunga chakudya, kupanga mankhwala apakatikati, kupanga utoto wa utomoni ndi kukonzekera mankhwala tsiku ndi tsiku, propionic acid yathu yadziwika bwino pamsika ku Southeast Asia, Middle East, Europe ndi madera ena. Potengera njira yonse yogawa zinthu ndi gulu la akatswiri otumiza mankhwala kunja, timathandizira kulongedza zinthu mwamakonda, kukonza maoda mosinthasintha komanso kupereka mankhwala kwa nthawi yayitali, ndipo nthawi zonse timapatsa makasitomala mayankho azinthu zopangira mankhwala otsika mtengo komanso chithandizo chogula chimodzi chokha.
