Abstract:

The present Technical Report No. VI, covering the quarter September 1 to November 30, 1950, in continuation of the trend developed in the previous quarter, discusses the preparation and evaluation of phosphonates as potential lubricants andor hydraulic fluids, to the exclusion of phosphinates and phosphine oxides, as the latter two classes of compounds have not appeared promising. The total numbers of preparations of this period are as follows phosphine oxides, 0 total for six quarters, 10 phosphinates, 0 19 phosphonates, 18 53 phosphates, 0 2 miscellaneous, 1 11 grand total, 19 95. The number of phosphonates 18 can be broken down in this manner 2 monophosphonates for use as intermediates 3 monophosphonates for evaluation 6 polyphosphonates for evaluation, of which 4 were bis-compounds and 7 repeated syntheses of promising compounds as bottoms-products, that is, the materials were not distilled. The latter were evaluated to ascertain whether or not they still retained their favorable characteristics on elimination of the tedious molecular distillation to which they had previously been subjected. In general, this they appeared to do very satisfactorily in the bench scale evaluations which are continuing. Motor Laboratory evaluations have been accelerated, still using commercial materials for orientation studies in Pesco gear pumps, cold and hot Lauson engines and spur gear load carrying capacity tests.
