Abstract

A soldering fluid comprises (a) a polyphenyl ether of the formula <FORM:1114349/C6-C7/1> where n is an integer from 2 to 6, R is hydrogen or a C1- 4 alkyl group, the R's being the same or different and (b) 1-50% by weight of a polyphenyl ether carboxylic acid of the formula <FORM:1114349/C6-C7/2> where n is an integer from 2 to 5, x is 0-3, y is 0-3 and x+y is 1, 2 or 3, the y's for each benzene ring being the same or different. In the example soldering fluids are described in which an isomeric mixture of polyphenyl ethers comprising 5 benzene rings and predominating in m-bis (m-phenoxyphenoxy) benzene is mixed with dicarboxylic acids derived from such an isomeric mixture of polyphenyl ethers (see Division C2).ALSO:The invention comprises polyphenyl ether carboxylic acids of the formula <FORM:1114349/C2/1> where n is an integer of 2-5, x is 0, 1, 2 or 3, y is 0, 1, 2 or 3 and x + y is 1, 2 or 3, the y's for each benzene ring being the same or different. In an example a polyphenyl ether dicarboxylic acid is obtained by brominating an isomeric mixture of unsubstituted polyphenyl ethers comprising 5 benzene rings and predominating in m - bis(m - phenoxyphenoxy)benzene, converting the dibromides obtained to a Grignard reagent with magnesium, carbonating with dry CO2 and acidifying with dilute HCl to free the carboxylic acid. Several additional polyphenyl ether carboxylic acids are specified. Such products are employed in soldering fluids (see Division C7).
