    • This invention is a fuel composition comprising a major amount of base fuel and at least 3% w/w of an ester additive mixture derivable by reacting together either (a) (i) a saturated, aliphatic polyhydric alcohol having three or more primary alcohol groups, (ii) a C2-C15 saturated, aliphatic branched chain monohydric alcohol and (iii) a saturated, aliphatic C4-C10 dicarboxylic acid, or (b) a saturated aliphatic polyhydric alcohol having three or more primary alcohol groups with a C6-C15 saturated, aliphatic straight chain or branched chain monocarboxylic acid, or (c) a C2-C15 branched chain saturated aliphatic alcohol with a saturated, aliphatic dicarboxylic acid having 6-10 carbon atoms. The ester additive has a boiling point ≧150° C., a molecular weight ≧200 and an oxygen content ≧13% by weight of said ester additive mixture. The additive significantly reduces particulate emissions from the exhausts of diesel powered engines.

    • Alkyl aromatic compounds are converted to alkyl aromatic aldehydes by a carbonylation reaction. The carbonylation catalyst can be a high boiling point carbonylation catalyst which allows for the separation of the aldehyde product by selective volatilization. Alternatively, the carbonylation catalyst can be selected from perfluoroalkyl sulfonic acids having 2 to 18 carbon atoms, perfluoroether sulfonic acids having 2 to 18 carbon atoms, BF3(ROH)x wherein R represents CH3 or H and X is a number within the range of from 0.2 to 2, GaBr3, GaCl3, TaF5, NbF5, and NbBr5, with the proviso that when the catalyst is TaF5, NbF5, or NbBr5, then the reaction takes place in the absence of added HF. Preferably, all of the carbonylation reactions take place in the absence of added HF. The alkyl aromatic aldehydes can be oxidized to form an aromatic acid. A mixed xylene feed stock can be converted to a mixture of dimethylbenzaldehydes and then oxidized to form trimellitic acid without the need to separate the xylene or dimethylbenzaldehyde isomers.
    • 烷基芳族化合物通过羰基化反应转化成烷基芳族醛。 羰基化催化剂可以是高沸点羰基化催化剂,其允许通过选择性挥发来分离醛产物。 或者,羰基化催化剂可以选自具有2至18个碳原子的全氟烷基磺酸,具有2至18个碳原子的全氟醚磺酸,BF 3(ROH)x其中R表示CH 3或H,X是在 0.2至2,GaBr 3,GaCl 3,TaF 5,NbF 5和NbBr 5,条件是当催化剂为TaF 5,NbF 5或NbBr 5时,则在不加入HF的情况下进行反应。 优选地,所有的羰基化反应都在不加入HF的情况下进行。 烷基芳族醛可被氧化形成芳族酸。 混合二甲苯原料可以转化成二甲基苯甲醛的混合物,然后氧化形成偏苯三酸,而不需要分离二甲苯或二甲基苯甲醛异构体。

    • Phenol-containing streams are treated by an oxygen-alkylation process to convert substantially all of the phenol groups to ether groups. The oxygen-alkylation process comprises contacting the phenol-containing stream, preferably a coal liquid, with (a) a basic solution comprising one or more oxides or hydroxides of a metal selected from the group consisting of alkali and alkaline-earth metals; and (b) an alkylating agent represented by the formula RX where R is a C.sub.1 to C.sub.18 alkyl, allyl, cycloalkyl, haloalkyl, benzyl or arylalkyl group provided X is located on the alkyl portion of the compound and X is sulfate or a halide selected from the group consisting of chlorine, bromine and iodine.
