Indlela ye-Propionic Acid Titration
Lungisa izinto zeglasi ezifana ne-burette kunye neflaski yekhonical. Ukuthatha umlinganiselo womxholo we-propionic acid kwiimveliso ze-propionic acid zoshishino njengomzekelo, linganisa ngokuchanekileyo ubunzima obuthile besampuli ye-propionic acid uze uyibeke kwiflaski yekhonical. Yongeza inani elifanelekileyo lamanzi acociweyo ukuze unyibilikise isampuli ngokupheleleyo. Emva koko khetha isalathisi esifanelekileyo, njenge-phenolphthalein. Titrate ngesisombululo esiqhelekileyo se-sodium hydroxide soxinzelelo olwaziwayo. Ngexesha le-titration, kwenzeka impendulo yokungapheleli phakathi kwe-sodium hydroxide kunye ne-propionic acid. Njengoko kongezwa i-sodium hydroxide, i-pH yesisombululo iyanda kancinci kancinci. Isiphelo se-titration sifikelelwa xa umbala wesisombululo utshintsha ukusuka ekubeni nombala ukuya kubomvu obukhanyayo kwaye uhlala ungatshintshi kangangesiqingatha somzuzu. Ngokusekelwe kumthamo wesisombululo esiqhelekileyo se-sodium hydroxide esisetyenzisiweyo, umxholo we-propionic acid kwisampuli unokubalwa kusetyenziswa ubudlelwane be-stoichiometric. Ifomyula ethile ithathwe kwi-equation yekhemikhali elinganiselayo yempendulo phakathi kwe-propionic acid kunye ne-sodium hydroxide, enomlinganiselo we-stoichiometric we-1:1, oguqulwa kusetyenziswa uxinzelelo lwe-molar kunye neefomyula zobunzima.info@pulisichem.cn

I-Shandong Pulisi Chemical Co., Ltd. Intshayelelo ekhethekileyo ye-Propionic Acid
I-Shandong Pulisi Chemical Co., Ltd. igxile ekunikezeni nasekusasazeni i-Propionic Acid yodidi lwemizi-mveliso kunye nodidi lokutya lwe-CAS 79-09-4. Njengoko yamkela uhlolo olusemgangathweni lwemveliso kunye neenkqubo ezingqongqo zokuhlola izinto eziluhlaza, i-propionic acid yethu inobunyulu obuphezulu, umxholo wokungcola okuphantsi kunye neempawu zomzimba ezizinzileyo kunye neekhemikhali, ihambelana ngokupheleleyo nemigaqo yokhuseleko lwemizi-mveliso kunye nokutya kwamazwe ngamazwe.
Isetyenziswa kakhulu ekuthinteleni ukubola kokutya, ukugcinwa kokutya, ukwenziwa kwe-pharmaceutical intermediate synthesis, ukwenziwa kwe-resin yepeyinti kunye nokulungiswa kwezinto eziluhlaza zekhemikhali zemihla ngemihla, i-propionic acid yethu ifumene ukuqatshelwa okuzinzileyo kwimarike kulo lonke elaseMzantsi-mpuma Asia, eMbindi Mpuma, eYurophu nakwezinye iindawo. Sithembele kwinkqubo epheleleyo yokwabiwa kwezinto kunye neqela leenkonzo zokuthumela ngaphandle iikhemikhali, sixhasa ukupakisha okwenziwe ngokwezifiso, ulungiselelo lwe-odolo oluguquguqukayo kunye nobonelelo oluzinzileyo lwexesha elide, kwaye sihlala sibonelela abathengi ngezisombululo zezinto eziluhlaza zekhemikhali ezingabizi kakhulu kunye nenkxaso yokuthenga enye indawo.
