    Abstract: PREPARATION OF TRI-SUBSTITUTED HYDROCARBYL PHOSPHATES, BY REACTING DIHYDROCARBYLCHLOROPHOSPHATES WITH ALCOHOLS IN THE PRESENCE OF CAUSTIC ALKALIS, SUCH AS CAUSTIC SODA AND CAUSTIC POTASH, ETC., WHEREBY THE HYDROEN CHLORIDE FORMED SIMULTANEOUSLY IS NEUTRALIZED QUICKLY WITH THE CAUSTIC ALKALI. ACCORDING TO THIS PROCESS, IT IS POSSIBLE NOT ONLY TO PREVENT THE DECOMPOSITION OF DIHYDROCARBYLCHLOROPHOSPHATES BUT ALSO TO SUPPRESS THE SIDE REACTION REPRESENTED BY THE EQUATION:

    (RO)3PO+HCL-->(RO)2P(O)OH+RIL

    WHEREIN R IS AN ALKYL GROUP. THE COMPOUNDS PRODUCED BY THE INVENTION ARE USEFUL AS ADDITIVES FOR GASOLINE, PLASTICIZERS FOR THERMOPLASTIC RESINS AND FLAME RETARDING AGENTS FOR RIGID POLYURETHANE FOAM, POLYESTER RESIN, ETC.

    Abstract: Fuel and lubricant compositions contain as additives at least one of the following pairs of additives: (A) [R-(OCH2CH2)x-O]3P = O and (B) (I) AND (II) (C) (III) AND (IV) where R is C8-18 alkyl, R1 is C4-18 alkyl, R2 is H or alkyl (at least two R2's being alkyl and the total number of carbon atoms in the total R2's being 5-36), R3 is H or methyl, x is 3-10, y is 2-12, and z is 2-20; or any of these pairs of compounds in which one or two equivalents of ethylene oxide in at least one of the ingredients is or are replaced by propylene oxide. Small amounts of the corresponding chlorides may be present. Any of the compositions may contain a small amount of an amine, particularly a higher tert-alkyl primary amine, present as excess during the preparation of the phosphorus compounds, the amine having been introduced to neutralize HCl. The base oil of the fuels may be gasoline, jet fuel oil, diesel fuel oil or furnace oil; and for the lubricants may be any of a variety of mineral oils, a spindle oil, an hydraulic oil, dioctyl or dinonyl adipate, azelate or sebacate, or, when the composition is to be used as an hydraulic fluid, a phosphate ester. The lubricants may be gelled to form greases.ALSO:Mixtures of neutral and acidic phosphoric acid esters of formulae [R-(OCH2CH2)x-O]3P = O and where R is the residue of nonyl phenol, dinonyl phenol, dodecyl phenol, tridecyl alcohol, or a mixture of myristyl, cetyl and stearyl alcohols, and x varies from 3 to 9 in various specific products are prepared by reacting 1 mole of phosphorus oxychloride with 3-3.5 mole of the ethylene oxide condensate of the alcohol or phenol.
