摘要： Polymerization inhibitor compositions are provided. The polymerization inhibitor compositions may include at least one hydroxylamine of a nitroxide and at least one phenylenediamine. Methods of inhibiting the unwanted polymerization of monomers are also provided. The methods include adding the presently disclosed polymerization inhibitor compositions to a fluid containing the monomers. The monomers may be ethylenically unsaturated monomers, such as acrylic acid, methacrylic acid, acrylonitrile, methacrylonitrile, acrolein, methacrolein, acrylate, methacrylate, acrylamide, methacrylamide, vinyl acetate, butadiene, ethylene, propylene, and styrene.

摘要： An apparatus comprises a first controller configured to control at least the flow rate of a polymerization inhibitor or acrylonitrile product to a first location where the two are mixed. The apparatus comprises a first on-line analyzer configured to measure polymerization inhibitor concentration in the acrylonitrile product at a second location, the second location downstream of the first location. The first on-line analyzer is configured to provide information relating to the measured inhibitor concentration at the second location to the first controller, the first controller configured process the information from the first on-line analyzer and to adjust at least a first operating parameter of a first addition device if the measured inhibitor concentration at the second location is outside a first predetermined condition. A second controller and a second on-line analyzer are provided to provide similar control of water addition to acrylonitrile product.

摘要： An optically active 2-cyano-2-methyl-alkanoic acid represented by the formula: ##STR1## is produced by optical resolution of the corresponding racemic mixture thereof with an optically active amine and is reduced to provide an optically active 2-cyano-2-methyl-1-alkanol represented by the formula: ##STR2## wherein R.sub.1 denotes an alkyl groups having 3-10 carbon atoms, R.sub.2 denotes an alkyl group having 2-10 carbon atoms and C* denotes an asymmetric carbon atom. These compounds are characterized by having a CN group with a large dipole moment directly attached to an asymmetric carbon atom and are effective for controlling the liquid crystal state of a liquid crystal composition when added thereto.
