At the DSB meeting on 21 April 2006, Mexico informed the DSB that it would need a reasonable period of time to implement the DSB`s recommendations and decisions in this case. On 22 June 2006, the United States informed the DSB that, to date, discussions between the parties had not allowed it to reach agreement on the reasonable period of time for Mexico to comply with the DSB`s recommendations and rulings. Therefore, the United States requested that the reasonable period of time be set by a binding arbitration procedure pursuant to Article 21.3(c) of the DSU. On 3 July 2006, Mexico and the United States informed the DSB that they had agreed, by mutual agreement, that the reasonable period of time for Mexico to comply with the recommendations and decisions of the DSB would be nine months and eight days and expire on 1 January 2007. However, the Mexican Congress issues between December 1 and December 31, 2006, the reasonable period is ten months and seven days and expires on January 31, 2007. In light of this agreement, the United States withdrew its request for arbitration pursuant to Article 21.3(c) of the DSU. Sodium carbonate (soda) was manufactured by the Leblanc process until 1880, when the much cheaper Solvay process became available. BASF ended its own manufacturing and then bought it from Solvay.  BASF is an acronym for Baden aniline and soda factory.
It was founded by Friedrich Engelhorn on 6 April 1865 in Mannheim, in the German-speaking region of Baden. Engelhorn was responsible in 1861 for the construction of a gas plant and street lighting for the city council. The gas plant produced tar as a by-product used by Engelhorn for the manufacture of dyes. BASF was founded in 1865 to produce other chemicals needed to produce dyes, including soda and acids. However, the facility was built on the other side of the Rhine near Ludwigshafen because the city of Mannheim feared that air pollution from the chemical plant would disturb the city`s residents. In 1866, the dye manufacturing processes were also moved to the BASF site.  In September 2019, BASF signed an agreement with DuPont Safety & Construction, a subsidiary of DuPont Co., for the sale of its Inge GmbH ultrafiltration membrane business. According to BASF executives, Inge GmbH and its products are more in line with DuPont and its business strategy.  William Henry Perkin`s discovery in 1857 that animin could be used to produce intense dyes led in England to the commercial production of synthetic dyes from animin, obtained from coal tars.
BASF was the first research director of Heinrich Caro, a German chemist experienced in the dye industry in England.  Caro developed a synthesis for alizarin (a natural pigment in krapp) and applied for a British patent on June 25, 1869. It so happens that on June 26, 1869, Perkin applied for a virtually identical patent and the two companies agreed on a reciprocal trade agreement on the procedure.  On July 28, 1948, an explosion took place at a BASF site in Ludwigshafen, killing 207 people and injuring 3818.  In 1952, BASF was refounded under its name at the request of former NSDAP member and head of military economics Carl Wurster. Carl Wurster led the production of Degesch`s Cyclone B.  With the German economic miracle in the 1950s, BASF included plastics such as nylon in its range. . . .
