ABSTRACT:
This invention relates to a process for the isomerization of branched dienes which comprises contacting at isomerization conditions a branched diene with a boron phosphate catalyst wherein the initial ratio of phosphorus (P) to boron (B) is less than 1.0 but greater than 0.6. The contacting is conducted at a temperature of from 100.degree. C. to 450.degree. C. and at a pressure from subatmospheric to superatmospheric.
