All-PPTA, tri-dimensional foamed consolidated FRP composite was prepared by embedding Kevlar 49 fibers in poly(A,A-di-sec-butyl-p-phenylene terephthalamide) resin [95]. The latter, on heating in the presence of benzenesulfonic acid catalyst, was dealkylated to form the PPTA matrix. In this way, Kevlar 49/PPTA molecular composites containing fiber fractions in the range of 8-40% by volume, having densities in the range of 0.2 to 1.2 g/cm, were prepared and their thermal and mechanical properties characterized. It has been pointed out that such all-PPTA composites mimic natural materials, e.g., the foamed composites prepared in this work had a remarkable resemblance to wood, with the advantages of flame and rot resistance.

The precise experimental conditions used can greatly influence the efficiency, or even the course, of the Ritter reaction. Representative procedures are available, along with a comprehensive tabular survey to 1966, in the article by Krimen and Cota. Optimum reaction times (typically 1-24 h) and temperatures (typically 20-50 °C) depend very much on e particular cases. Typical temperatures of 0-10 °C are used when hydrogen cyanide or hydrogen fluoride are employed. Benzenesulfonic, fluoroboric, formic, hydrofluoric, methanesulfonic, perchloric, phosphoric, polyphosphoric, sulfuric, toluenesulfonic and tri-fluoromethanesulfonic acids are amongst those used to generate the carbenium ion. However, the majority of workers favor sulfuric acid and, in cases where comparative studies have been carried out, - ... 

In spite of their similarity potassium hydroxide and sodium hydroxide differ in their effects. Potassium benzenesulfonate and potassium hydroxide give an almost quantitative yield of phenol, but only a partial yield is obtained in sodium hydroxide. This relationship is, however, reversed when one tries to convert benzenetrisulfonic acid into phloroglucinol with potassium hydroxide...
