Literature Melting Points of Some Organic Compounds

WebThe thermometer of this apparatus was calibrated using benzoic acid as one standard. An experimental melting point (calibrated) concerning 184°C for the unknown acid was measured. This value highest closely correlated because the literature melting point of p-anisic acid, one of the possible twenty compounds the the list. WebProcedure to determine the melting point of Benzoic Acid: Take Benzoic acid on a tile and crush it into a fine powder. Take a capillary tube and by heating one end close the end of the tube. Hold the closed end of the capillary tube between your finger and thumb as shown in figure (a) above. Dip the open end of the capillary tube in the finely ... WebIt is commercially manufactured by the chemical reaction of toluene (a hydrocarbon obtained from petroleum) with oxygen at temperatures around 200° C (about 400° F) in the presence of cobalt and manganese salts as catalysts. Pure benzoic acid melts at 122° C (252° F) and is very slightly soluble in water. east west bank fremont
