Number: 585/801
Name: Chemistry of hydrocarbon compounds > Purification, separation, or recovery > By conversion of solid to gas, e.g., sublimation, etc., or by melting or squeezing out liquid from solid natural source
Description: Subject matter wherein hydrocarbon contained in a solid material (including a fluent solid) is converted to a gas without existing in the liquid state for any significant amount of time, or wherein the hydrocarbon is recovered as a liquid by application of heat or pressure to a solid source of the hydrocarbon found in nature, e.g., recovery of turpentine from wood, etc.
