Über acidimetrische Titration und Zusammensetzung der Handelsmilchsäure

Abstract: Aus dem Dipenten wurde mit Bromwasserstoff-Eisessig wieder Es wurde weiter Plantagenkautschuk bei 300° im Vakuum destil-fast quantitativ das Dihydrobromid ausgeschieden. liert mit folgendem Resultat : 50 gr Plantagenkautschuk gaben 28 gr Destillat + 21 gr Ruckstand, 100 gr Plantagenkautschuk gaben 47 gr Destillat + 49 gr Ruckstand. 100 gr Plantagenkautschuk im Kohlendioxydstrom bei 300° lieferte 29 gr Destillat und durch nachtragliches Erhitzen im Vakuum wurden noch 15 gr hohersiedende Zersetzungsprodukte erha… Show more

“…Wherever possible, acid solutions were analyzed by colorimetric titration with standard base. When the concentration of lactic acid in water solution is above about 20% analysis, it is complicated by the presence of a self-polymer of lactic acid (3,10). In this case, excess base was added to the solution and the mixture was heated for about 10 minutes in a boiling water bath.…”
