    • Condensation products made by reacting an .alpha.-hydroxyalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The total number of carbon atoms in the non-fused hydrocarbyl substituents is at least about 7 while the .alpha.-hydroxyalkyl group contains from 1 to about 36 carbons and the olefinic acid or nitrile reactant usually contains 2 to about 40 carbon atoms. Products made from hydroxymethyl alkyl-substituted phenols and .alpha.,.beta.-olefinic acid derivatives such as maleic anhydride are particularly useful. Similarly useful post-treated products can be made from these condensation products by further reaction with alcohols, amines, metal salts or metals.
    • 通过使具有至少一个非稠合烃基取代基的α-羟基烷基羟基 - 芳族化合物与至少一种烯属腈,羧酸或羧酸衍生物反应制得的缩合产物可用作燃料和润滑剂的添加剂。 非稠合烃基取代基中的碳原子总数为至少约7,而α-羟基烷基含有1至约36个碳,并且烯属酸或腈反应物通常含有2至约40个碳原子。 由羟甲基烷基取代的酚和α,β-烯烃酸衍生物如马来酸酐制成的产品是特别有用的。 类似地,有用的后处理产物可以通过与醇,胺,金属盐或金属的进一步反应从这些缩合产物制备。

    • Carboxylic acid esters of the formula (I), ##STR1## wherein X is a hydrogen atom, or a C.sub.1 -C.sub.3 alkyl or a C.sub.1 -C.sub.3 alkoxyl group or a halogen atom linked to the meta or para position and R.sub.1 is a group of the formula (II) or (III), ##STR2## wherein R.sub.2 is a hydrogen atom or a methyl group, and when R.sub.2 is a methyl group R.sub.3 is also a methyl group, and when R.sub.2 is a hydrogen atom R.sub.3 is a group of the formula, ##STR3## (wherein R.sub.5 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, vinyl or a C.sub.1 -C.sub.3 alkoxymethyl group, R.sub.6 is a hydrogen or halogen atom or a methyl group, or, taken together, R.sub.5 and R.sub.6 may form a tetramethylene group by connecting together at ends thereof), R.sub.4 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxyl or 3,4-methylenedioxy group, n is 1 or 2 and Y is a isopropyl or cyclopropyl group. These carboxylic acid esters are produced by reacting the reactive derivatives of a carboxylic acid represented by the formula, ##STR4## wherein R.sub.1 is a group of the formula (II) or (III), ##STR5## wherein R.sub.2, R.sub.3, R.sub.4, n and Y are as defined above, and Z is a halogen atom, with an alcohol of the formula (IV), ##STR6## wherein X is as defined above, in the presence of an acid-binding agent. These carboxylic acid esters are useful as insecticides and acaricides.
