Abstract
The invention relates to the manufacture of reactors for Oxo synthesis which are constructed of steel having a Brinell hardness of less than 300 and containing 1 to 6% chromium and 0.4 to 0.7% molybdenum.
Claims8
An oxo reactor for carrying out oxo synthesis comprising:
- a. vertical tubes,
- b. means coupling the tops and bottoms of said vertical tubes, said tubes and coupling means being formed of steel having a Brinell hardness of less than 300 and including in said steel 1-6% chromium and 0.4-0.7% molybdenum,
- c. inlet means for introducing the oxo reagents into the reactor and structured to result in immediate mixing of said reagents introduced into the reactor, and
- d. the steel used in making said coupling means being different from the steel used in making said vertical tubes and having a higher chromium content.
