Title: Complex carbonated metal salts of alkyl phenol sulphides
IPC: C10L1/24
Filed: 1957-10-17
Abstract: The invention comprises fuel oils and gasolines containing complex carbonated metal salts prepared from <FORM:0825315/III/1> where R is C5-C24 alkyl, x is 1-4, Y is 0-3 Z is 1-5, and Ba(OH)OR1, NaOR1 or Mg(OR1)2 where R1 is C1-C4 alkyl and carbon dioxide, so that the final products contain from at least 0.2 to at least 0.6 equivalents of carbon dioxide based on the equivalents of phenol hydroxyl, and at least 1.8 to 2.6 equivalents of metal per equivalent of phenolhydroxyl.  Proportions of the additive specified are 0.0003-0.008% by weight in gasoline and 0.0003-0.0006% by weight in fuel oil.  Specification 744,942 is referred to.ALSO:The invention comprises complex carbonated metal salts of alkyl phenol sulphides prepared by reacting an alkyl phenol sulphide of general formula <FORM:0825315/IV (b)/1> where R is C5-C24 alkyl group, X is 1-4, Y is 0-3, and Z is 1-5, with Ba(OH)OR1NaOR1 or Mg(OR1)2, where R1 is C1-C4 alkyl group, so that there are at least 1.2-1.6 equivalents of metal per equivalent of phenyl hydroxyl in the sulphide reactant, increasing the temperature of the reaction mixture and passing in sufficient CO2 to incorporate in the complex salt product from at least 0.2 to at least 0.6 equivalents of CO2 based on the phenyl hydroxyl in the said product, reducing the temperature and reacting the product with a further amount of metal alcoholate in order to supply 0.6-1.0 equivalents of metal per equivalent of phenol hydroxyl, raising the temperature again and filtering to obtain the complex carbonated metal phenate sulphide salt.  The process may be carried out in the presence of a hydrocarbon solvent, and the reaction may be carried out at 80-200 DEG  C. Examples of the process of the invention are given in which the following starting materials are used, BaOH(OCH3) magnesium dimethylate, sodium methylate, and dodceylphenol, diamylphenol and dinonylphenol sulphides.  Comparative examples mention the use of barium hydroxide octahydrate. Specification 744,942 is referred to.ALSO:The invention comprises complex carbonated metal salts of alkyl phenol sulphides prepared by reacting an alkyl phenol sulphide of general formula <FORM:0825315/IV (a)/1> where R is C5-C24 alkyl group, X is 1-4, Y is 0-3, and Z is 1-5 with Ba(OH)OR1 NaOR1 or Mg(OR1)2, where R1 is C1-C4 alkyl group, so that there are at least 1.2-1.6 equivalents of metal per equivalent of phenyl hydroxyl in the sulphide reactant, increasing the temperature of the reaction mixture and passing in sufficient CO2 to incorporate in the complex salt product from at least 0.2 to at least 0.6 equivalents of CO2 based on the phenyl hydroxyl in the said product, reducing the temperature and reacting the product with a further amount of metal alcoholate in order to supply 0.6-1.0 equivalents of metal per equivalent of phenol hydroxyl, raising the temperature again and filtering to obtain the complex carbonated metal phenate sulphide salt.
