Title: A Process for Preparaing 5<1>-Purinenucleotides.
IPC: C07H19/20
Filed: 1966-07-13
Abstract: 1,159,813. Purine nucleotides. TAKEDA CHEMICAL INDUSTRIES Ltd. 13 July, 1966 [14 July, 1965], No. 31541/66. Heading C2C. The 5<SP>1</SP>-monophosphates and/or 5<SP>1</SP>-diphosphates of inosine, guanosine and adenosine and the corresponding 2<SP>1</SP>-deoxy derivatives are prepared by reacting an acetate of guanine, hypoxanthine or adenine with a tertiary amine salt of 1,2,3-triacetylribose-5-monophosphate or 1,3 - diacetyl - 2 - deoxyribose - 5 - monophosphate with heating and deacetylating the resulting product. Suitable tertiary amines include pyridine, pyrimidine, picoline, quinoline and triethylamine. The reaction is preferably carried out by melting the reactants (suitably 2 moles of the amine salt to 1 of the monophosphate) at 100 C.-190 C. for 10-60 minutes at atmospheric or reduced pressure. ZnCl 2 , AlCl 3 , BF 3 , H 2 SO 4 , p-toluene-sulphonic acid or sulphamic acid may be present as catalyst. The reaction may also be carried out in a flux such as acetic or benzoic acid or cresol in an amount from 10-250% by weight of the starting materials. The deacetylation of the acylated nucleotide may be carried out (a) by treatment with aqueous ammonia at room temperature or under reflux, (b) by stirring in methanolic ammonia or (c) by refluxing in methanolic sodium methoxide. The final product may be recovered in the free state or, for example, as the sodium, potassium or ammonium salt. The purinenucleoside-5<SP>1</SP>-mono and diphosphates may be separated by fractional crystallization, treatment with anion exchange resin or active charcoal or extraction with a suitable organic solvent. The tertiary amine salts used as starting materials may be prepared by allowing an acetylating agent such as (CH 3 CO) 2 O or CH 3 COCl to react with the corresponding ribose-5-monophosphate at relatively low temperature in the presence of excess tertiary amine, or by firstly acetylating and then adding the amine.

Abstract: 661,557. Casting stereotype. ARCHER, A. J. Dec. 22, 1949, No. 32806/49. Class 100 (ii). A machine for casting flat stereotype plates comprises a casting chamber contained between platens 33, 74, Fig. 3, a metal pot 69, a pump 64 actuated by a drive shaft 67 through pinion 63 and rack 65, and a vessel 73 into which metal is forced by the pump as well as into the casting chamber through orifice 71, so that the pressure of metal in vessel 73 forces metal evenly upwards in the casting chamber. The platen 33 is pivoted on a shaft 53, and cam 54 releases a thrust rod 56 before filling the casting chamber, so that spring 60 causes platen 33 to swing on shaft 53 and bring orifice 71 into engagement with nozzle 68. Slidable along a slideway 32 on the platen 33 are four casting gauge carriers 34, 35, Figs. 1 and 3, having hooked legs 36-39, in which rest pivots 40 carried in wrought pivot holders 41, 42 screwed to the casting gauge assembly. The platen 74 has a counterweight 76 and is carried on a fulcrum aligned with pivots 40 and supported on the platen 33. The platen 74 can thus be swung outwards on its fulcrum, and the casting gauge assembly can also be swung about the pivots 40 for insertion of the matrix. The casting gauge assembly comprises four pairs of superimposed gauge members 1, 5; 6, 7; 8, 9; 10, 11. The member 1 has a slot 2 in which slides a retaining plate 4 screwed to one end of the member 5, which has a similar slot in which slides a similar plate 12 screwed to the member 1 at 18. The plate 12 is screwed at 17 to a plate 13 sliding in a slot in the member 6 and screwed at 19 to the member 7. Similar slidable joints are provided at the four corners of the casting chamber. The holders 41, 42 are screwed to the plate sliding in the member 10, and to the member 6. The members 11, 6 rest in grooves in carriers 50, 51 slidable along a slideway 49 on the platen 33. A piece 43 is screwed to member 11 and a similar piece 46 is screwed to the back of member 6. A weir 20 slidable in a groove in the platen 33 divides the casting chamber into a casting cavity 22 and a flow spreading chamber 21 communicating with the orifice 71, and is secured between a matrix holder and the member 6 at 25 and also to the member 6 at 26. The matrix is secured between the matrix holder and weir and in recesses in the members 5, 7, 11. The size of the cavity 22 can be varied for casting a given range of sizes of plate by adjusting the gauge members. Thus, the height of the cavity is varied by vertical sliding of members 10, 7, carrying with them members 8, 9. The width is varied by horizontal sliding of members 1, 9, 6, 7 with respect to members 5, 8, 10, 11, either set of members being moved.
