Title: Improvements in or relating to refining hydrocarbon oils
Inventor: KRAUSE JACK HARRY
IPC: C10G27/08
Filed: 1952-02-21
Abstract: Mercaptans are removed from a sour hydrocarbon distillate boiling in the range about 325-about 650 DEG F. without the formation of colour greater than about 1 N.P.A. therein by contacting the distillate, in admixture with about 1-15 per cent by volume of an aqueous solution of KOH having a concentration of about 50-60 per cent and about 0.004-0.1 per cent by weight of copper in the form of a copper compound active as an oxidation catalyst, with an oxygen-containing gas at a temperature of about 80-125 DEG F. and separating spent KOH solution and associated reaction products from the treated distillate.  The copper compound must be introduced by addition to the KOH solution prior to admixture with the distillate or by addition to a mixture of the KOH solution and the distillate.  The spent KOH solution may be allowed to settle so that potassium cresylates separate out as a distinct layer which is then removed. The spent KOH solution may then be regenerated by distillation and employed for the treatment of additional quantities of hydrocarbon distillate.  Hydrocarbon distillates mentioned are heavy naphthas, kerosene, heater oil and furnace oils derived from straight-run crude petroleum distillation or from cracking processes, either thermal or catalytic.  The oxygen-containing gas, which may be air or oxygen, may be employed in an amount which is 1 1/2 -2\ba1/2 times that theoretically required for converting mercaptans present in the hydrocarbon distillate to disulphides.  In the case of air, the sweetening treatment may be carried out at 25-200 p.s.i.g., but the use of increased pressure is not ordinarily necessary in the case of oxygen.  The copper may be added in the form of an aqueous solution of a copper salt such as copper chloride, sulphate, nitrate or acetate.  The copper salt solution may be added directly to the KOH solution if the latter is hot enough to avoid formation of a black precipitate.  When added in this way, for example to boiling KOH solution, a blue compound is formed which is believe to be colloidal copper oxide.  The copper salt solution may also be added to an intimate mixture of the KOH solution and the hydrocarbon distillate. Air or oxygen may then be introduced into the mixture or alternatively, the air may be introduced into the hydrocarbon distillate and KOH before adding the copper salt.  The hydrocarbon distillate may be given a preliminary wash with an alkaline solution, e.g. sodium hydroxide or carbonate, to remove H2S, while the sweetened distillate may be passed through a fibrous or finely granular material such as glass wool, rock wool or sand, and then washed with water, in order to remove traces of KOH a small amount of a metal deactivator such as N, N1-disalicylidene-1, 2-diaminopropane may be added to the sweetened distillate.  Specifications 728,057, 745,632 and 745,633 are referred to.
Patent GB-636331-A (GB)
Title: A method of producing 4-aminosalicylic acid
Filed: 1947-02-17
Abstract: p-Aminosalicylic acid (2-hydroxy-4-amino-benzoic acid) is prepared by heating 6-nitro-benzisoxazole carboxylic acid (4-nitro-2-oxyphenyl-glyoxime), or a derivative thereof resulting from substitution in the carboxylic group, e.g. an alkyl ester or amide, in the presence of sulphuric acid and reducing the resultant 4-nitrosalicylic acid.  In examples: (1) the methyl ester of 6-nitrobenzisoxazole-3-carboxylic acid is heated with sulphuric acid to give 4-nitrosalicylic acid, which is reduced to the amino compound, either by hydrogenation in the presence of a platinum catalyst or by means of tin and hydrochloric acid; (2) the free acid is used in place of the methyl ester in (1) and (3) the amide is used in place of the methyl ester in (1).  It is stated in the Specification to be known that nitrobenzisoxazole-3-carboxylic acid methyl ester is hydrolysed by mineral acids such as hydrochloric acid, to give 4-nitrosalicylic acid at temperatures considerably above 100 DEG  C.  The Specification as open to inspection under Sect. 91 comprises also the preparation of derivatives p-aminosalicylic acid arising from further substitution in the benzene ring thereof.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Liebigs Annalen der Chemie, Volume 390, page 3.
