In order to take advantage of the combustion step, the naphthalate diester is selected to produce an appropriate alcohol byproduct that has a volatility comparable to or greater than that of water. There are several ways of expressing this selection. As a first, the naphthalene diester can be selected on the basis of being one that will produce an alcohol byproduct that is selected form the group consisting of methanol (CH3OH, b.p. 64.5° C.), ethanol (CH3CH2OH; b.p. 64.5° C.), propanol (CH3CH2CH3OH; b.p. 78.3° C.), and isopropanol (CH3CHOHCH3 ; 82.5° C.), all of which have boiling points less than that of water and thus the appropriate volatility. Other possible alcohol byproducts that define qualifying naphthalene diesters, include secondary butanol (CH3CH2CHOHCH3 ; b.p. 99.5° C.) and tertbutanol ((CH3)3COH; b.p. 83° C.). Naphthalene diesters that produce isobutenal ((CH3)2CHCH2OH; b.p. 108° C.) and tertpentanol (CH3CH2C(OH)(CH3)2 ; b.p. 102° C.) are also candidates although their boiling points slightly exceed that of water at atmospheric pressure.
