Abstract: Provided is a production process for a carbonized product characterized by comprising the following steps (a) to (b): (a) a step in which metal-made or ceramic-made plural granular matters are charged into a heat treating apparatus which is maintained at a temperature of 400° C. or higher and 700° C. or lower and allowed to move therein and in which a carbonized product precursor is fed into the above apparatus and subjected to heat treatment, whereby the carbonized product is adhered on the surface of the above granular matters and (b) a step in which the carbonized product adhered on the surface of the granular matters is heated at a higher temperature than the heat treating temperature in the step (a) and 900° C. or lower, whereby the carbonized product is separated from the granular matters. The present invention provides a production process for an inexpensive and useful carbonized product by simple apparatus and steps.

Abstract: A process for production of 2,6-dimethylnaphthalene is disclosed, comprising the steps: (1) an acylation step where p-tolyl sec-butyl ketone is produced from toluene, n-butene and carbon monoxide: (2) a hydrogenation step where the carbonyl group of the p-tolyl sec-butyl ketone is hydrogenated: and (3) a dehydrogenation and cyclization step where the hydrogenated product obtained above is subjected to dehydrogenation and cyclization to produce the desired 2,6-dimethylnaphthalene. The process enables efficiently producing a high quality or high purity 2,6-dimethylnaphthalene.
