JW Weiler & Cie.

from Wikipedia, the free encyclopedia

JW Weiler & Cie was an aniline and nitric acid factory founded October 1, 1861 by the businessman Joseph Wilhelm Weiler (1819–1875). It was on Venloer Strasse in Ehrenfeld near Cologne . The plant, which was based on the reduction of nitrobenzine according to Bechamp, supplied the newly founded dye producers in the lower Rhine area with ever larger quantities of aniline. The company expanded very quickly. After the sudden death of the founder (1875), his son Dr. Julius Weiler (1850–1904), chemistry with Adolf (von) Baeyerhad studied management. In 1880 the share of German aniline production was already around 35%, and by 1886 the capacity of aromatic amines had reached 1200 tons. In 1880 the production of nitric acid began in the Müngersdorf factory and in 1881 the Wöllner'sche sulfuric acid factory in Cologne-Riehl, which had existed since the 1940s, was taken over. In 1889 it was converted into a stock corporation with a capital of 2,125,000 marks and was henceforth called "Chemische Fabriken, vorm. JW Weiler & Cie ". In 1889, the explosives factory "Wittener Roburit Factory" , founded in 1887 in Annen by the merchants Heinrich Korfmann and Ewald Franke, was taken over.

In a self-portrayal from 1893 it says: It manufactures aniline and related products as the raw material for paint production and is the oldest and one of the most important of its kind. It has branches in Cologne-Müngersdorf and Riehl . Starting from the products of tar distillation , it produces the hydrocarbons of the benzene series , their nitro derivatives , as well as dinitrobenzene and binitrotoluene , aniline , the toluidines , xylidines , naphthylamine and aniline salt and supplies all these products in a state of perfect purity to the paint industry. The nitric and sulfuric acids required for their needs , whatever acids they sell, they produce themselves. Part of the production is exported to the United States.

In 1896 she merged with her best customer, the Uerdingen company Teerfarbenfabrik Dr. E. ter Meer & Cie under the name "Chemical factories - formerly Weiler-ter Meer". In order to improve logistics, the production of aromatic amines was completely relocated to Uerdingen and the Ehrenfeld location was closed.

This construct became part of the interest group of the German tar paint factories in 1916 and of IG Farben in 1925 .
