Soil improvement agent composition

A surfactant composition for agricultural chemicals, containing fatty acid polyoxyalkylene alkyl ether expressed by the following general formula (I),RCO(EO)(PO)OR&#x2003;&#x2003;(I)wherein the fatty acid polyoxyalkylene alkyl ether has a narrow ratio of 55% by mass or more, where the narrow ratio is expressed by the following formula (A):Narrow ratio=&#x3a3;&#x2003;&#x2003;(A).

Surfactant composition for agricultural chemicals

A water-insoluble cutting fluid base oil or grinding fluid base oil for metalworking includes a fatty acid polyoxyalkylene alkyl ether represented by the following formula (I-A), wherein a hydroxyl value of the fatty acid polyoxyalkylene alkyl ether is less than or equal to 2.0 mgKOH/g.R&#x2014;CO-(OA)-OR&#x2003;&#x2003;(I-A)(In the formula (I-A), Rrepresents a linear or branched, saturated or unsaturated monovalent hydrocarbon group having 15 to 21 carbon atoms and Rrepresents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 8 carbon atoms. In addition, A represents an alkylene group having 2 to 4 carbon atoms, OA represents alkylene oxide, and n represents 1 to 6 which is an average mole number of added alkylene oxide (AO)).

Metalworking fluid base oil

The present invention relates to a method for producing an unsaturated aliphatic primary amine including subjecting an unsaturated aliphatic nitrile having 16 to 22 carbon atoms to hydrogen reduction in the presence of ammonia using a hydrogenation catalyst to produce an unsaturated aliphatic primary amine, wherein 0.01 parts by weight to 1.0 part by weight of aromatic carboxylic acid amide is added based on 100 parts by weight of the unsaturated aliphatic nitrile, and a partial pressure ratio of ammonia to hydrogen is adjusted to 8/2 to 6/4. The present invention also relates to an unsaturated aliphatic primary amine, which is produced by the production method.
