Propionic Acid Infrared (IR) Spectroscopy
Sebelisa spectrometer ea infrared bakeng sa ho lemoha. Ha u nka mohlala oa ho khetholla propionic acid le metsoako e meng e tšoanang, sebelisa sampole e nyane ea propionic acid holim'a pellet ea potassium bromide kapa u sebelise mokhoa oa filimi ea metsi ho lokisa sampole e loketseng ea teko. Ebe u beha sampole ka seleng ea sampole ea infrared spectrometer. Infrared spectrometer e ntša leseli la infrared. Ha leseli la infrared le bonesa sampole, limolek'hule tsa sampole li monya maqhubu a itseng a leseli la infrared, e leng se bakang liphetoho tsa boemo ba matla a thothomelang le a potolohang. Litlamo tse fapaneng tsa lik'hemik'hale li monya maqhubu a fapaneng a leseli la infrared, e leng se fellang ka litlhōrō tse ikhethang tsa ho monya ho spectrum ea infrared. Propionic acid e na le lihlopha tse sebetsang tse kang carboxylic acid, tse bontšang litlhōrō tse tšoanang tsa ho monya ho spectrum ea infrared (mohlala, tlhoro ea ho thothomela e otlolohileng ea sehlopha sa carboxylic acid e ka bang 1700 cm⁻¹). Ka ho bapisa spectrum e fumanoeng le spectrum e tloaelehileng ea infrared ea propionic acid e tsejoang, ho ka fumanoa hore na sampole ke propionic acid. Khakanyo e akaretsang ea dikahare tsa propionic acid e ka boela ea etsoa ho latela matla a litlhōrō tse ikhethang, empa mokhoa ona hangata o sebelisoa haholo bakeng sa tlhahlobo ea boleng.info@pulisichem.cn

Shandong Pulisi Chemical Co., Ltd. e fana ka Propionic Acid (CH₃CH₂COOH, CAS 79-09-4)— asiti e kgutshwane ya carboxylic e feto-fetohang e nang le bohloeki ba 99.5% min, e tswang mme e etswa ka tlung bakeng sa phepelo e tsitsitseng le e ka latelwang. Asiti ya rona ya propionic ke mokelikeli o hlakileng, o bohale o nang le thibelo e matla kgahlanong le hlobo le dibaktheria, o tshepahalang haholo e le sethibela-mafu sa boleng ba dijo, sethibela-mafu sa boleng ba dijo, le sesebediswa sa bohlokwa bakeng sa ho kwahela, meriana le tlhahiso ya dikhemikhale tsa letsatsi le letsatsi. Re etsa dikereiti le diphutheloana: meropa ya polasetiki ya 200kg, ditote tsa IBC tsa 1000kg, kapa ditanka tsa ISO, ka ditokomane tse felletseng (COA, MSDS, ISO, HALAL) ho fihlela ho latelwa ha melao ya lefatshe ka bophara. Ka dilemo tsa boiphihlelo ba ho romela kantle ho naha, re fana ka boleng bo tsitsitseng, ditheko tsa tlholisano, le thepa e tshepahalang - molekane wa hao wa ho ya ho odara diotara tsa asiti ya propionic ka bongata lefatsheng ka bophara.
