In chemistry , work-up refers to the series of manipulations required to isolate and purify the product(s) of a chemical reaction . The term is used colloquially to refer to these manipulations, which may include:
4-438: Workup may refer to: Workup (chemistry) , manipulations carried out after the main chemical reaction to secure the desired product Workup, a game of practice baseball (see scrub baseball ) Topics referred to by the same term [REDACTED] This disambiguation page lists articles associated with the title Workup .

8-400: A work-up. The Grignard reaction between phenylmagnesium bromide ( 1 ) and carbon dioxide in the form of dry ice gives the conjugate base of benzoic acid ( 2 ). The desired product, benzoic acid ( 3 ), is obtained by the following work-up: This dehydration reaction produces the desired alkene ( 3 ) from an alcohol ( 1 ). The reaction is performed in a distillation apparatus so
12-407: The formed alkene product can be distilled off and collected as the reaction proceeds. The water produced by the reaction as well as some acid will co-distill, giving a distillate mixture ( 2 ). The product is isolated from the mixture by the following work-up: The reaction between a secondary amine ( 1 ) and an acyl chloride ( 2 ) yields the desired amide ( 4 ) as shown below. The acyl chloride
