Indlela Yokulinganisa I-Propionic Acid
Lungisa izinto zokugqoka ingilazi ezifana ne-burette neflaski eliyi-conical. Uma uthatha isinqumo sokuqukethwe kwe-propionic acid emikhiqizweni ye-propionic acid yezimboni njengesibonelo, sikala ngokunembile isisindo esithile sesampula ye-propionic acid bese usifaka eflaskini eliyi-conical. Engeza inani elifanele lamanzi acwengekile ukuze uncibilikise isampula ngokuphelele. Bese ukhetha inkomba efanelekile, njenge-phenolphthalein. Titrate ngesisombululo esijwayelekile se-sodium hydroxide sokuhlushwa okwaziwayo. Ngesikhathi se-titration, kwenzeka ukusabela kokungathathi hlangothi phakathi kwe-sodium hydroxide ne-propionic acid. Njengoba i-sodium hydroxide ingezwa, i-pH yesisombululo iyanda kancane kancane. Iphuzu lokugcina le-titration lifinyelelwa lapho umbala wesisombululo ushintsha usuka kokungagqami uye kokubomvu okukhanyayo futhi uhlala ungashintshi isigamu somzuzu. Ngokusekelwe kumthamo wesisombululo esijwayelekile se-sodium hydroxide esisetshenzisiwe, okuqukethwe kwe-propionic acid kusampula kungabalwa kusetshenziswa ubudlelwano be-stoichiometric. Ifomula ethile itholakala ku-equation yamakhemikhali elinganiselayo yokusabela phakathi kwe-propionic acid ne-sodium hydroxide, enesilinganiso se-stoichiometric esingu-1:1, esiguqulwa kusetshenziswa ukuhlushwa kwe-molar kanye namafomula esisindo.info@pulisichem.cn

I-Shandong Pulisi Chemical Co., Ltd. Isingeniso Esikhethekile se-Propionic Acid
I-Shandong Pulisi Chemical Co., Ltd. igxile ekuhlinzekweni nasekusatshalalisweni kwe-Propionic Acid yezinga lezimboni kanye nezinga lokudla i-CAS 79-09-4. Njengoba yamukela ukuhlolwa kokukhiqiza okujwayelekile kanye nezinqubo zokuhlola izinto zokusetshenziswa eziqinile, i-propionic acid yethu inezici zobumsulwa obuphezulu, okuqukethwe okuphansi kokungcola kanye nezakhiwo zomzimba nezimakhemikhali ezizinzile, ihambisana ngokugcwele nemininingwane yomhlaba wonke yezimboni kanye nokuphepha kokudla.
Isetshenziswa kabanzi ekuvimbeleni ukubola kokudla, ukulondolozwa kokudla, ukwenziwa kwemithi okuphakathi, ukwenziwa kwe-resin yopende kanye nokulungiswa kwezinto zokusetshenziswa zamakhemikhali nsuku zonke, i-propionic acid yethu ithole ukuqashelwa okuzinzile emakethe kulo lonke elaseNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi, eYurophu nakwezinye izifunda. Sithembele ohlelweni oluphelele lokwabiwa kwezinto kanye nethimba lezinsizakalo zokuthumela amakhemikhali kwamanye amazwe, sisekela ukupakisha okwenziwe ngokwezifiso, ukuhlelwa kwe-oda okuguquguqukayo kanye nokunikezwa okuzinzile kwesikhathi eside, futhi njalo sinikeza amakhasimende izixazululo zezinto zokusetshenziswa zamakhemikhali ezingabizi kakhulu kanye nokusekelwa kokuthengwa okukodwa.
