sulfonated with a sulfonating agent to form mono and disulfonated anhydropentitol esters finally in the third step the sulfonate moiety or moieties on the mono and disulfonated anhydropentitol esters are displaced by a primary amine compound having sufficient polarity to form an amphiphilic tetrahydrofuran compound in conjunction with the hydrophobic r group of the fatty acid each step in the process is believed to be novel and each of the compounds made by these steps are believed to be novel compounds accordingly the present disclosure has multiple aspects and multiple embodiments that will be understood from the description and figures that follow the first step of acylation can occur in two embodiments according to one embodiment depicted in fig3 the process involves acylation of one to three of u2014 oh moieties on the anhydropentitol by contacting a desired fatty acid halide compound containing 8 30 carbons at a certain temperature with the anhydropentitol compound in presence of a nucleophilic base for a time sufficient to form at least a mono or di fatty acid ester of the anhydropentitol as depicted in fig3 fatty acid chloride compounds are the exemplary fatty acid halide some tetrahydrofuran triesters are also formed but while such tetrahydrofuran fatty acid triesters have value in certain applications they are not useful for subsequent derivitizations to form amphiphilic compounds according to further aspects of this disclosure alcohol acylation can be effectuated by several carboxylic species such as but not limited to alkyl alkenyl alkynyl allyl and aryl carboxylic acids acid chlorides were chosen specifically in this disclosure for demonstrative purposes other halogenated fatty acid species will also work well acid chloride acylation can result in copacetic yields of corresponding pentitol mono di and tri esters as manifest in the forthcoming examples.
