Title: Cyclophosphates and their preparation
IPC: C07H19/10
Filed: 1971-06-08
Abstract: 1300196 Cyclic phosphate derivatives of pyrimidine or purine bases MERCK PATENT GmbH 8 June 1971 [1 July 1970] 19454/71 Heading C2P Novel cyclophosphates of the general formula in which R<SP>1</SP> is the radical of a pyrimidine or purine base, R<SP>2</SP> is H, OH or a functionally modified OH group, e.g. an esterified or etherified OH group and R<SP>3</SP> is H or a substituted or unsubstituted hydrocarbon radical containing a total of up to 10 carbon atoms, and their physiologically acceptable salts are obtained by cyclizing a compound of the general formula wherein R<SP>4</SP> and R<SP>5</SP> are aryloxy groups which may be halo- or negatively substituted by treatment with a base. The reaction conditions can be chosen so that the product obtained is a salt of the base used, e.g. the Na, K or Ba salt, and if desired the free acid can be liberated from the salt, e.g. by careful treatment with a mineral acid. Any functional groups present in the starting material which are sensitive to bases should be suitably protected before cyclization. and any protective groups may then be split off during the cyclization or later, e.g. by hydrolysis or hydrogenolysis. The main reaction is preferably carried out in the presence of water and/or one or more inert organic solvents. When the products are stable salts, e.g. the Na salts, they may be converted to other suitable salts by double decomposition or by means of an ion exchanger. Specified radicals R<SP>1</SP> are the radicals of adenine, guanine, thymine, xanthine, hypoxanthine, cytosine, uracil, 5-fluoro-uracil, 5- methyl-cytosine, and 5-hydroxymethyl cytosine. The radical R<SP>3</SP> may be substituted preferably by OH, amino, carboxy or carbalkoxy groups and together with the N atom shown may be a radical derived from a naturally occurring amino acid. The reaction can be effected by first treating with a weak base such as ammonia under gentle conditions to form a compound of Formula I but containing the radical R<SP>4</SP> or R<SP>5</SP> (such as p-nitrophenoxy) instead of the OH group and then splitting off the R<SP>4</SP> or R<SP>5</SP> radical by alkaline hydrolysis under vigorous conditions or by hydrogenolysis. The compounds II can be obtained by reacting a nucleoside 5<SP>1</SP>-tosylate of formula in which R<SP>6</SP> is p CH 3 C 6 H 4 SO 3  with an amine R<SP>3</SP>NH 2  and then treating the resulting ammonium tosylate with potassium tert.-butylate to form the free base (R<SP>6</SP> = R<SP>3</SP> - NH) which is then phosphorylated with a phosphoryl chloride of the formula R<SP>4</SP>R<SP>5</SP>POCl (e.g. bis-p-nitrophenyl phosphoryl chloride). The products I have therapeutic properties and may be used in admixture with solid, liquid and/or semi-liquid inert, physiologically acceptable carriers or excipients.

Title: Improvements in and relating to the treatment of hair for permanent waving
Filed: 1945-08-01
Abstract: Hair, particularly human hair, is given a permanent set, or stress is removed therefrom, by treating the hair with an aqueous sulphite solution having a pH value within the range from about pH 6 to pH 8 and containing from 15 per cent to 45 per cent by volume of a water-soluble monohydric alcohol or mixture of alcohols at a temperature below 50 DEG  C.  The sulphite solution may comprise a mixture of a sulphite and a bisulphite in proportions to give the desired pH value.  Sodium or potassium sulphite may be used with lithium or ammonium bisulphite.  Approximately equimolecular proportions of sulphite and bisulphite will in general give the specified pH condition.  The concentration is preferably within the range of two-thirds to one and one-third gram-molecule of sulphite and bisulphite together per litre.  Methyl, ethyl, propyl, or butyl alcohol may be used.  The monohydric alcohol may be used in admixture with a glycol such as ethylene glycol.  The sulphite solution may contain a surface active agent such as cetyl trimethyl ammonium bromide or cetyl pyridinium bromide. Kieselguhr or gum may be included as thickening agent.  For treating human hair on the head, the hair may be washed, dried, wound on curlers and then treated with the sulphite solution or it may be treated with the solution and then wound on curlers or formed into waves or curls.  In an example, the hair is treated with a solution containing 63 grams of sodium sulphite, 50 grams of ammonium bisulphite and 300 c.c. of ethyl alcohol per litre. The hair may be covered with a cap and left for 30 to 60 minutes without heating, or it may be heated by air or heated pads for 10-20 minutes at 35-45 DEG  C.  The hair is then washed and it may be further treated with a solution of a mild oxidizing agent, e.g. peroxide, persulphate, or perborate.  This solution may contain a cation-active compound such as cetylpyridinium bromide. Alternatively, the finishing treatment may be effected with a solution of cation-active compound without any oxidizing agent. Specification 456,336 is referred to.

Title: Improvements in or relating to the production of olefinic hydrocarbons by cracking wax and wax-containing materials and to the olefinic hydrocarbons so obtained
IPC: C10G9/00
Filed: 1949-07-28
Abstract: <PICT:0686000/III/1> Olefines having at least five carbon atoms in the molecule, are obtained by thermally-cracking hydrocarbon wax or mixtures containing hydrocarbon wax, in the vapour-phase at a temperature between 500 DEG C and 600 DEG C and preferably in the presence of steam; and by subjecting at least that part of the feed which is not initially flash-vaporized (at a temperature below 500 DEG C) to heat-treatment, called "soaking," at 390 DEG C to 450 DEG C for a period which decreases as the temperature increases and which varies from four hours at 390 DEG C to one-quarter-of-an-hour at 450 DEG C, submitting the treated material to flash-vaporization, and passing the vapours to the thermal cracking zone.  The process reduces the amount of evaporator-residue.  Slack wax at 100 DEG C is introduced through pipe 1 into the base of fractionator D where it mixes with hot recycle feed-stock; and the mixture at about 350 DEG C, flows through pipe 2 to preheater-coil 3 in furnace F, where it is raised to about 490 DEG C.  Thence the mixture passes by pipe 4 to flash-evaporator E where it mixes with five times it weight of steam at 440 DEG C and 60 to 90 p.s.i.g. introduced through pipe 5. The vapours leaving the evaporator are passed by pipe 6 to cracking-coil 7 wherein the temperature is about 550 DEG C, and cracking takes place in 1 to 3.5 seconds. the effluent from coil 7 is passed, together with quenching-water introduced through pipe 9, into fractionator D from the top of which is withdrawn a mixture rich in C9-C18 a-olefines.  The residue from the evaporator is passed through pipe 10 and coil 11 to soaking-tank S where it is maintained at 425 DEG C for 45 minutes.  A quantity of the residue equivalent to between 5 and 10 per cent of the fresh feed, is continuously bled-off through pipe 15.  The soaked residue is returned to the evaporator via pipe 12 and coil 3.
