THE SYNTHESIS AND EVALUATION OF AROMATIC ESTERS AS POTENTIAL BASE STOCK FLUIDS FOR GAS TURBINE ENGINE LUBRICANTS. Quarterly Progress Report No. 3 for May 1, 1960 to July 31, 1960

The program comprises the synthesis and evaluation of esters based on either aromatic polycarboxylic acids or aromatic polyols. Esters based on trimesic acid (1,3,5benzene tricarboxylic), terephthalic acid (1.4-benzene dicarboxylic), and diphenic acid (2,2'-biphenyl dicarboxylic) were synthesized and esterified with phenols of the benzyl type and 2.2-dimethyl substituted alcohols. A few derivatives were prepared from trimethylolanisole (1-methoxy-2, 4.6-trimethylolbenzene). These esters were evaluated for thermal stability in the 600 to 750 F temperature range. It was found that all esters containing a benzyl alcohol type structure are thermally unstable in the 600 to 700 F range, including the trimethylolanisole esters. Esters based on 2,2-dimethyl substituted alcohols exhibited a variable range of stabilities, depending on the acid used. It appeared that diphenic acid esters were considerably more stable than the corresponding trimesates or terephthalates. Esters of phenol appeared to be more stable than those of alkylated phenols and phenolic diphenates more stable than trimesates or terephthalates, which may be due, in part, to the greater ease of purification of the former.
