Filed: 1962-05-02
Abstract: Hydroxy-pyridines of formula: <FORM:0966805/C1/1> in which A and B are CHO, COOH, COOR1, CONH2, COX, CH2OR1, CN, CH2X, CH2NH2, CH2OH or CH2NHR, radicals (R1 is a hydrocarbon group and X is halogen) or A and B are hydrocarbon groups linked by an oxygen, nitrogen or sulphur atom, are prepared by intimately contacting 4-methyl -5- hydrocarbon oxyazoles with an ethylenic compound of formula A-CH=CH-B. Suitable ethylenic starting materials are, for example, maleic acid and fumaric acid and dialkyl esters thereof, fumaronitrile, fumaryl chloride and maleonitrile, or 2,5-dihydrofuran or in a modification of the process, maleic anhydride. When A and B are CH2OH groups the product is Vitamin B6 which may also be obtained by treating other products in known manner to convert the substituents A and B to hydroxymethyl groups. For example when A and B are carboxylic ester groups, or formyl groups they may be reduced with lithium aluminium hydride.  When the ethylenic starting material is 2,5-dihydrofuran the product is the internal ether of Vitamin B6. The process may be carried out at elevated temperature in the presence of a solvent. The products are isolated in the form of their hydrochloride salts from which the free bases may be obtained by treatment with an alkali. Examples are given of the preparation of (a) Vitamin B6; (b) the internal ether of Vitamin B6; (c) diethyl -2- methyl -3- hydroxypyridine-4, 5-dicarboxylate; (d) 2-methyl -3- hydroxypyridine-5-carboxylate; (e) 2-methyl -3- hydroxy-4, 5-dicyanopyridine; (f) 2-methyl -3- hydroxy-4, 5-dimethoxymethyl pyridine and (g) 2-methyl -3- hydroxy -4- formyl -5- hydroxymethyl pyridine.

Abstract: 841,001. Coking hydrocarbons. ESSO RESEARCH & ENGINEERING CO. May 30, 1958 [Aug. 7, 1957], No. 17314/58. Class 55 (1). In a process wherein heavy hydrocarbon oil is contacted at coking temperature with a fluidized bed of inert particulate solid material containing a superposed dilute phase, the oil being converted to vapourous products and carbonaceous solids being continuously deposited on the inert solid material in the coking zone, and wherein the vapourous products are removed through a cyclone separating zone at the upper portion of the dilute phase and at least a portion of the inert solid material is circulated to an external heating zone to increase its temperature, at least a portion of the heated inert solid material being recycled to the coking zone, undesired deposition of coke above the fluidized bed is reduced by injecting a minor portion of the recycled heated inert solid material to the upper portion of the dilute phase and a major portion into the lower portion of the dilute phase a short distance above the level of the fluidized bed, preferably against diffusing baffle means. Heavy crudes, atmospheric and vacuum bottoms from crude, pitch, asphalt and other heavy hydrocarbon petroleum residues or mixtures thereof may be treated. Suitable inert particulate solid materials are coke, spent catalyst, pumice, sand, kieselguhr, carborundum and alumina. As shown, a coking vessel 1 suitable for operation at 900‹ F. contains a bed of coke particles at 1125‹ F. which is fluidized by entry of a gas, e.g. steam, via pipe 3. A stream of solid particles is removed from the vessel 1 via line 8 to a heater (not shown). Crude oil enters the bed via line 2, preferably at a plurality of points in the system. The oil is thermally decomposed and the resulting vapours assist in the fluidization of the bed. Product vapours leave through cyclone 4 and line 6 and solids separated therefrom are returned to the bed through dip-leg 12. Hot coke particles are recycled from the heater through line 9 or several lines. A minor portion, e.g. 5-15%, enters, by way of line 7, the upper portion of dilute phase 11 adjacent to cyclone 4 and a major portion, e.g. 85-95%, enters, by way of line 13, the lower portion of the dilute phase and is dispersed by baffle 10.
