  • Patent number: 4284564
    Abstract: The present invention is directed to a process for the preparation of certain N-substituted-2-haloacetanilides via the reaction of a secondary 2-haloacetanilide with a haloalkyl ether, particularly, halomethyl ethers, which comprises forming the ether in situ by the in-solvent reaction of an alcohol, formaldehyde or other aldehyde and an acid halide to produce high purity haloalkyl ethers, while decreasing the concentration of undesirable bis by products, as for example bis(chloromethyl) ether. The ether formed in situ thereafter reacts with the secondary 2-haloacetanilide in the presence of a phase transfer catalyst and base to form the N-substituted-2-haloacetanilide.

  • Patent number: 4280833
    Abstract: This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polyurea, which involves bringing together an aqueous phase containing a lignin sulfonate emulsifier and a water-immiscible phase containing a water-immiscible material, the material to be encapsulated, plus polymethylene polyphenylisocyanate, dispersing the water-immiscible phase in the aqueous phase followed by addition of a polyfunctional amine. Polymethylene polyphenylisocyanate reacts with the amine to form a solid polyurea shell wall about the encapsulated material. The capsules formed may be directly used as aqueous suspensions.
