AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water. [2] The recent patent literature [3] describes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
Constructed with input data under the form of time series of station positions and Earth Orientation Parameters. [5] This version introduces extra parameters to describe the year-periodic motion of the stations: A (amplitude) and φ (phase) per-axis. This sort of seasonal variation has an amplitude of around 1 cm and is attributed to non-tidal ...
The manufacturing process involves reacting cyclohexanedimethanol with epichlorohydrin, using a Lewis acid as catalyst, to form a halohydrin. This is followed by washing with sodium hydroxide in a dehydrochlorination step to form the epoxide rings. [8] The waste products are water and sodium chloride and excess caustic soda.
