Title: Improvements in or relating to processes of and apparatus for treating fatty acid-containing stock
IPC: C11C1/10
Filed: 1941-02-14
Abstract: 547,168. Distilling fatty acids. STEVENS, A. H. (Armour & Co.). Feb. 14, 1941, No. 2040. [Class 32] Higher fatty acids, e.g. palmitic acid, are recovered from stock containing them, e.g. acidulated cotton seed foots, by preheating the stock and passing it into a fractionating column where the stock is stripped of its lighter fractions by steam and then passing the stock into a heated fractionating column where the fatty acids are distilled off under reduced pressure and in the absence of steam ; the residual stock from the second column is flashed with reduction of pressure and the residues returned to the bottom of the first column for further distillation with steam. The fatty acid stock is fed from a pipe 10 through a preheater A into the upper part of a fractionating tower B supplied at the bottom with steam through line 46. The vapours and steam are withdrawn through line 14 and condenser 15 to receiver D, part being returned as reflux to tower B by pump 41 and line 42. The stripped stock is removed through line 18 and trap 19 to the second fractionating tower E maintained under a pressure of 2mm. of mercury and heated at the bottom by a Dowtherm heater 20. Vapours formed are condensed in condenser 22 while the bottoms are withdrawn through line 26 to a flash drum F which may be heated by circulating part of the diphenyl used as heating medium in heater 20 through a coil 31. Residual stock from the drum is fed through line 33 back to the tower B where it is further stripped with steam before being withdrawn through line 34. The vapours formed in the flasher pass throhgh entrainment eliminators 27 and are condensed in condenser 29. Condensers 29 and 22 are connected by header 30 to the vacuum pumps 45. In the example the stock is heated to 450‹ F. in the heat exchanger and stripped with steam under a pressure of 50 mm. Hg. The tower F is heated at its base to 482‹ F. and maintained under a pressure of 2 mm. Hg. Palmitic acid is recovered in the condenser 22.

Title: A process for the separation of monoalkyl phosphates from dialkyl phosphates
IPC: C07F9/11
Filed: 1954-01-29
Abstract: Monoalkyl phosphates are separated from dialkyl phosphates, the alkyl groups containing not less than 5 and not more than 18 carbon atoms and preferably 7 to 12 carbon atoms, by converting the monoalkyl and dialkyl phosphates into their calcium or magnesium salts, and dissolving the salts of the dialkyl phosphates from the mixture of salts so formed by extraction with one or more non-polar or slightly polar organic liquids. Specified organic liquids are hydrocarbons, e.g. pentane, benzene, cyclohexane and gasoline fractions.  In examples: (1) a normal aqueous solution of sodium hydroxide is added to the products obtained by reacting phosphorus pentoxide with 3,5,5-trimethylhexanol and any unreacted nonanol is then removed by steam distillation.  A solution of calcium nitrate is then added to the mixture to precipitate the monononyl and dinonyl phosphates in the form of their calcium salts.  The precipitate is filtered off, dried, and then extracted at 18 DEG  C. with pentane whereby the calcium salt of the dinonyl phosphate is dissolved from the mixture, leaving a residue consisting of the calcium salt of the monononyl phosphate and some calcium phosphate; (2) as in (1) except that the extraction is applied to the product obtained by reacting phosphorus pentoxide and n-heptanol-1.
