Abstract: Discoloration of dicarboxylic acid chlorides having 4 to 10 carbon atoms, especially those made by reacting the corresponding dicarboxylic acid with phosphorus trichloride, is inhibited by the addition of a dicarboxylic acid thereto. Addition of a dicarboxylic acid to a dicarboxylic acid chloride which has already discolored precipitates impurities and thus clarifies the dicarboxylic acid chloride. The clarified dicarboxylic acid chlorides are useful as starting materials to make polyester foam materials.

Abstract: A measurement system that uses a laser triangulation device to measure the thickness of transparent and/or opaque layers of a multilayer film. The triangulation device has a laser device that projects a beam perpendicularly to a surface of the multilayer film and first and second detectors that image first and second reflected rays of the beam at first and second distances offset from first and second optical axes to produce first and second measurement signals. A controller processes the measurement signals using a triangulation procedure and a simultaneous equation procedure to provide a thickness of an outer transparent layer. For a multilayer film having an opaque layer sandwiched between outer transparent layers, first and second triangulation devices are disposed on opposed sides of the film to measure the thickness of each outer film. Knowing the distance between the two devices, the thickness of the opaque layer can be derived.
