Qhov sib txawv tseem ceeb ntawm anhydrous thiab monohydrate citric acid yog qhov anhydrous citric acid tsis muaj dej ntawm crystallization whereas monohydrate citric acid muaj cov dej molecule txuam nrog ib tug citric acid molecule.
Citric acid yog cov organic acid tsis muaj zog, yog li, peb tuaj yeem pom nws nyob hauv cov txiv hmab txiv ntoo citrus. Cov neeg tsim khoom tsim cov kua qaub ntau hauv ib xyoos vim nws muaj ntau yam siv; raws li ib tug acidifier, raws li ib tug flavoring thiab chelate agent. Cov tshuaj no tuaj yeem muaj nyob hauv daim ntawv tsis muaj dej (dawb dej) lossis raws li daim ntawv monohydrate.
YAnhydrous Citric Acid yog dab tsi?
Anhydrous citric acid yog daim ntawv tsis muaj dej ntawm citric acid. Cov tsos ntawm cov compound no tsis muaj xim, thiab nws tsis muaj ntxhiab. Nws tsis muaj dej hauv nws daim ntawv qhuav, granulated. Peb tuaj yeem tsim cov tshuaj no los ntawm crystallization los ntawm dej kub.
Daim duab 01: Citric Acid tshwm sim hauv txiv qaub thiab lwm cov txiv hmab txiv ntoo citrus
Cov ntawv citric acid anhydrous los ntawm daim ntawv monohydrate ntawm 78 ° C. Qhov ceev ntawm daim ntawv anhydrous yog 1.665 g / cm3. Nws melts ntawm 156 ° C, thiab lub boiling point ntawm no compound yog 310 ° C. Cov tshuaj formula ntawm no compound yog C6H8O7 thaum molar mass yog 192.12 g / mol.
Monohydrate Citric Acid yog dab tsi?
Monohydrate citric acid yog cov dej uas muaj citric acid. Nws muaj ib tug dej molecule txuam nrog ib tug citric acid molecule. Peb hu cov dej no ua dej ntawm crystallisation. Daim ntawv no ntawm citric acid ua los ntawm crystallization los ntawm dej txias.
Daim ntawv monohydrate hloov mus rau hauv daim ntawv anhydrous ntawm 78 ° C. Qhov ceev ntawm qhov sib xyaw no yog 1.542 g / cm3. Cov tshuaj formula ntawm no compound yog C6H8O7H2 O, thiab molar mass yog 210.138 g / mol. Lub melting point yog 135 ° C, thiab lub boiling point yog 310 ° C.
Qhov txawv ntawm Anhydrous thiab Monohydrate Citric Acid yog dab tsi?
Anhydrous citric acid yog cov dej tsis muaj citric acid tab sis, monohydrate citric acid yog cov dej uas muaj citric acid. Qhov no yog qhov sib txawv tseem ceeb ntawm anhydrous thiab monohydrate citric acid. Tsis tas li ntawd, cov tshuaj formula ntawm anhydrous citric acid yog C6H8O7 Cov molar loj ntawm no 192.12 g / mol. Peb tuaj yeem tsim cov compound no los ntawm crystallization los ntawm dej kub. Ntawm qhov tod tes, cov tshuaj formula ntawm monohydrate citric acid yog C6H8O7H 2O, thiab molar mass yog 210.138 g / mol. Tsis tas li ntawd, peb tuaj yeem tsim cov tshuaj no los ntawm crystallization los ntawm dej txias.
Summary – Anhydrous vs Monohydrate Citric Acid
Citric acid muaj nyob rau hauv ob daim ntawv ua anhydrous daim ntawv thiab monohydrated daim ntawv. Qhov sib txawv ntawm anhydrous thiab monohydrate citric acid yog tias anhydrous citric acid tsis muaj dej ntawm crystallization whereas lub monohydrate citric acid muaj ib tug dej molecule txuam nrog ib tug citric acid molecule.
