Benzoic Acid Melting Point Range
Benzoic acid c6h5cooh is a colourless crystalline solid and the simplest aromatic carboxylic acid. Salts of benzoic acid are used as food.
Benzoic Acid For Synthesis Sigma Aldrich
C the temperature that melting occurred was 123 for benzoic acid confirming the accuracy of the me c l temp s readings.
Benzoic acid melting point range. Appreciable amounts have been found in most berries around 0. It is the simplest aromatic carboxylic acid the name is derived from gum benzoin which was for a long time its only source benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. Before the samples were placed in the mel temp it was first calibrated using benzoic acid which has a melting point range of 122 123.
Find product specific information including cas msds protocols and references. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.
