Tax-free diesel fuel is intended for off-road uses such as agricultural operations, but illicit use of this fuel does occur and is a convenient way of evading payment of excise taxes. Current enforcement to prevent this practice involves visual inspe

A synthesis and isolation scheme is described for producing mono alkyl esters of methylphosphonic acid based upon stoichiometric addition of alcohol to methylphosphonic dichloride. Solvent extraction is applied to the reaction mixture to separate the
