摘要： A hydrocarbon conversion process which utilizes a solid phosphoric acid catalyst having a total X-ray intensity of at least 40 percent relative to alpha-alumina. The solid phosphoric acid catalyst is produced by crystallizing an amorphous mixture of an acid oxide of phosphorus and a siliceous material at a temperature of from 350.degree. to 450.degree. C. and in the presence of from 10 to 50 mole percent water vapor based upon the total vapor rate to the crystallizing means. Embodiments of the new hydrocarbon conversion process include alkylation, oligomerization, and hydration, of hydrocarbons and oxygenated hydrocarbons.
