摘要:
The invented process for producing sorbic acid includes the step of decomposing a polyester at temperatures of 100° C. or less with hydrochloric acid, which polyester is obtained from ketene and crotonaldehyde. In the process, the reaction temperature after the initiation of a polyester decomposition reaction is controlled by adding a hydrochloric acid to a reaction mixture, which hydrochloric acid has a temperature lower than that of the reaction mixture, for example, a temperature of 50° C. or less. Such hydrochloric acid for reaction control may have a concentration of, for example, 23% by weight or more. This process can yield sorbic acid in a short time in a high yield and can highly efficiently produce sorbic acid.
摘要:
The invented process produces sorbic acid or its salt through the decomposition of a polyester obtained from ketene and aldehyde, and includes the step of treating a solution containing-sorbic acid or its salt with a chemically activated carbon, which sorbic acid or its salt is produced by the decomposition of the polyester. The treatment with activated carbon is performed, for example, at pH ranging from 5.8 to 7.5 at temperatures ranging from 30° C. to 80° C. The invented process can efficiently remove colored substances and can easily yield a high quality sorbic acid having a satisfactory hue in a high yield.
摘要:
This invention provides a pressure sensitive adhesive composition comprising an acrylic copolymer component (A) which is at least in part an acetoacetyl group-containing acrylic copolymer and at least one curing component (B) selected from the class consisting of isocyanate compounds, epoxy compounds, aldehyde compounds, non-amino resin amine compounds, metal salts, metal alkoxides, metal chelate compounds, ammonium salts and hydrazine compounds.This adhesive composition is well-balanced in the triad of tack, adhesion, cohesion in adhesion technology and can be advantageously used in various applications such as adhesive tapes and labels.
摘要:
The multistation switch system comprises position detector for detecting current position of a main shaft, programmable switch device provided for each of the stations for receiving position data formed in accordance with output of the position detector and generating, in response to the position data, one or more on/off signals which are predetermined in correspondence to selected position or positions of the main shaft, and start/stop interlock circuit for setting start and stop timings for starting and stopping a switch output in correspondence to the programmable switch device provided for each station. The programmable switch device for each station outputs the on/off signals between the start and stop timings set by the start/stop interlock circuit in correspondence to each station.
