Title: Hydrolysis of vinyl ethers
IPC: C07C45/51
Filed: 1947-05-05
Abstract: Aldehydes and ketones of the formula R1CH2.CO.R2, where R1 and R2 are hydrogen, alkyl, aryl, or aralkyl, are prepared by hydrolysis of unsaturated ethers of the formula R1CH = C.R2(OR), where R is alkyl, aryl or aralkyl, with steam in the vapour phase in the presence of a solid dehydration acid catalyst, having a concentration of alkali metal or alkaline earth metal ions less than 0.1 per cent, at an elevated temperature.  The temperatures may be between 30 DEG  and 250 DEG  C., preferably 80-200 DEG  C., and normal, high or reduced pressure may be used.  Acetaldehyde is a preferred product when the initial ether is a vinyl ether of an aliphatic alcohol, e.g. methyl, lauryl or cyclohexyl alcohol, or an aromatic hydroxy compound, e.g. phenol or benzyl alcohol. Other aldehydes are produced from ethers of, for example, propenyl, butenyl and styrenyl alcohols, and ketones are produced from ethers of such compounds as isopropenyl, isobutenyl, a -phenylvinyl, or a -benzylvinyl alcohols.  An alcohol ROH is formed in addition to the carbonyl compound produced in the reaction, and a certain amount of the acetal of the aldehyde may also be formed.  The initial ether may be mixed with acetals, alcohols, acetylene, or ethylene.  2-4 Mols. of water per mol. of ether are preferably used, with a contact time of 1-2 seconds. The alkali ion concentration is preferably less than 0.01 per cent and is obtained by acid washing of the catalyst.  Specified catalysts are acid-washed silica gel and alumina, chromium and other oxides on inert carriers such as pumice, and, for preference, tungstic oxide.  In the examples, (1-4) acetaldehyde and the corresponding alcohol ROH are produced from ethyl, methyl and n-butyl vinyl ethers, and (5) acetone is prepared from isopropenyl methyl ether.

Title: Organic phosphate, salts thereof, and process for the manufacture thereof
Inventor: MORRISON ALEXANDER LANG
IPC: C07F9/58
Filed: 1955-04-29
Abstract: The invention comprises pyridyl-(3)-methyl dihydrogen phosphate and alkali metal, alkaline earth metal and ammonium salts thereof. The products may be obtained by phosphorylating pyridyl-(3)-methyl alcohol by treating it with a mixture of phosphorus pentoxide and phosphoric acid at an elevated temperature, hydrolysing any polyphosphates contained in the resulting mixture by heating same in acid solution, passing the hydrolysate through a cationic exchange resin and separating off that fraction of the eluate which contains the required pyridyl-(3)-methyl dihydrogen phosphate and, if desired, treating same with a precipitating agent or, where a salt is required, carrying out the defined process and treating said fraction or the pyridyl-(3)-methyl dihydrogen phosphate precipitated therefrom with an alkali metal hydroxide, alkaline earth metal hydroxide or ammonium hydroxide followed by isolation of the resulting salt by precipitation or concentration.  The phosphorylation may suitably be conducted at 60 DEG  C. and hydrochloric acid may conveniently be used in the hydrolysis step.  Suitable cationic exchange resins are sulphonic acid resins in their acid form.  Acetone may be used as the precipitating agent in either case.  Before feeding the hydrolysate on to the column containing the cationic-exchange resin it is preferred to remove the bulk of inorganic oaterial contained therein by treating it with phenol and partitioning the phenolic layer between ether and water.  The resulting aqueous layer contains the required product and is then fed on to the column.  Examples are given for the production of the pyridyl-(3)-methyl dihydrogen phosphate and its mono- and disodium salts.  The products are stated to be effective vasodilators.

Patent GB-435747-A (GB)
Title: Preparation of metallic beryllium and its alloys
IPC: C22B35/00
Filed: 1935-04-29
Abstract: In a process for making beryllium alloys by the reduction of reducible beryllium compounds by an alloy of magnesium with the metal less electropositive than beryllium, which it is desired to alloy with beryllium, alkali double fluorides are used containing less alkali fluoride in proportion to the beryllium fluoride than is indicated by the formula BeF2.2NaF.  Examples of such metals are copper, aluminium, or zinc.  An alloy of zinc and beryllium thus obtained may be re-melted in a flux of equal parts barium chloride and fluoride, to distil off the zinc and leave molten beryllium. Beryllium alloys may be formed with any metal that is capable of alloying with zinc and not volatile at 1300 DEG  C., for instance iron or nickel.  For example, a zinc alloy containing 17,1 per cent magnesium and 6,13 per cent iron is melted in a crucible with BeF3.NaF resulting in a yield of a zinc-iron-beryllium alloy containing 7 per cent beryllium and 7 per cent iron, with 1 to 3 per cent magnesium.  This alloy is heated to 1300 DEG  C. in a suitable flux and yields an alloy containing 50 per cent iron and 50 per cent beryllium.  A copper-beryllium alloy containing 12 per cent of beryllium is obtained by adding a copper-magnesium alloy containing 26,7 per cent of magnesium to BeF2.NaF in a crucible heated to 1000 DEG  C. from which is poured a copper alloy containing 11 per cent beryllium and 3 per cent magnesium, the latter alloy being re-melted to get rid of the magnesium.  Alloy of iron and nickel containing about 50 per cent beryllium are also referred to.
