One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.
The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution. Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.
The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a <u>positive result </u>will look like <em><u>the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.</u></em>
