Abstract: PROCESS FOR THE MANUFACTURE OF ISOPRENE BY CANALYTIC DEHYDRATION OF 3-METHYL-3-BUTEN-1-OL IN THE PRESENCE OF CALCIUM PHOSPHATE AS CATALYST AT ELEVATED TEMPERATURES, WHEREIN DEHYDRATION IS CARRIED OUT, PREFERABLY IN THE PRESENCE OF STREAM, AT TEMPERATURES BETWEEN 200* AND 300*C. USING A 3-METHYL-3-BUTEN-1-OL HAVING A PURITY OF A LEAST 85% BY WEIGHT BASED ON THE TOTAL WEIGHT OF OXYGEN-CONTAINING ORGANIC COMPOUNDS PRESENT IN THE STARTING MATERIAL. ISOPRENE IS AN IMPORTANT MONOMER, FOR EXAMPLE IN THE PRODUCTION OF SYNTHETIC RUBBER.
