Number: 585/956
Name: Chemistry of hydrocarbon compounds > Miscellaneous considerations > Condition-responsive control and related procedures in alicyclic synthesis and purification
Description: Cross-reference collection of purification and alicyclic synthesis processes (under unnumbered subclass MISCELLANEOUS CONSIDERATIONS) involving a step of taking a measurement, sensing a condition, or making a test, or controlling an operating condition of the process in response to a condition different from that controlled, e.g., flow rate of feed in response to temperature of effluent, etc.
