Title: A process for the manufacture of calcium salts of phosphorylated arabonic acid and derivatives thereof
IPC: C07F9/02
Filed: 1947-08-06
Abstract: Calcium salts of phosphorylated arabonic acid and derivatives thereof are obtained by treating arabonic acid lactone, arabonic acid, its salts or carboxyl esters with a phosphorylating agent and treating an aqueous solution of the product obtained with a calcium salt (including calcium hydroxide) to effect a double decomposition reaction with the said product and isolating the said calcium salts of phosphorylated arabonic acid or derivatives thereof from the mixture thus obtained.  The monophosphoric acid obtained by the esterification of one molecule of arabonic acid with one molecule of phosphoric acid is preferred because it gives a calcium salt of calcium to phosphorus ratio of 2 : 1 which is also soluble within the pH range of stomach juice and hence is suitable for therapeutic purposes.  Phosphorylating agents specified are phosphorus oxychloride, concentrated phosphoric acid and dibenzyl phosphate, although when the latter compound is used hydrogenation is necessary to remove the benzyl groups.  Basic organic solvents, e.g. pyridine, may be used optionally with an inert diluent, e.g. dioxane.  The phosphorylated compounds thus obtained are monoesters of phosphoric acid, each molecule of which may contain one or more monoesterified phosphoric acid radicles. They are converted to their calcium salts as indicated above.  In examples, arabonolactone in pyridine is treated with an approximately equimolecular quantity of phosphorus oxychloride in (1) pyridine, and (2) dioxane at low temperatures, water is added to dissolve the pyridine hydrochloride formed and the solution is decolourized with charcoal and made just alkaline with calcium hydroxide when the calcium salt formed is filtered off and purified by dissolving in acid and reprecipitating with alkali at pH 7.

Filed: 1956-07-17
Abstract: 842,003. Electric tests. BRITISH THOMSON-HOUSTON CO. Ltd. Aug. 22, 1957 [July 17, 1956], No. 22117/56. Class 40 (1). Oil is tested for contamination by comparing its thermal conductivity when subjected to an electric field of one polarity with that when the polarity is reversed. Change in conductivity is an indication of contamination. As shown, the oil is in a brass cylinder 1 sealed at either end and having a platinum resistance wire 2 extending axially through it. The wire constitutes one arm of a bridge circuit of which the ratio arms are constituted by resistors R1 and R2 and the fourth arm by standard resistor T in series with variable resistor R3. In operation, source P applies rectangular pulses between the brass case and the control wire. The bridge is then balanced by means of variable resistor R3 and the current in standard resistor T measured by potentiometer P1. Switch R is then changed over to reverse the polarity of the pulses applied to the oil. Unbalance of the bridge D1 indicates that the conductivity of the oil and consequently the resistance of platinum wire 2 have changed and that the oil is contaminated.
