  • Patent number: 5223477
    Abstract: Microcapsule formulations are combined with emulsions or particle dispersions in a single-package formulation which is storage-stable and provides substantially the full efficacy of each of the two forms as if applied individually. The single-package formulation is suspension having two dispersed phases--the first being an active species encapsulated in a shell of inert polymeric diffusion-limiting material (i.e., a microcapsule), and the second being an active species in water-insoluble form with no diffusion-limiting barrier at its surface. An appropriate suspension system is included to prevent the dispersed phases from agglomerating within themselves and with each other. The invention is useful in combining two different active ingredients as well as in combining immediate-delivery and delayed-delivery forms of the same active ingredient.

  • Patent number: 5214211
    Abstract: Rare earth pillared clays, and especially cerium and lanthanum aluminum chlorohydrite pillared clays, are quite effective catalysts in the alkylation of diaryl amines at temperatures in the range of 100.degree.-225.degree. C. The catalysts effect alkylation using olefins as the alkylating agent with high conversion and with minimal cracking of either the olefin or the alkylated product. Catalysts may be regenerated by heating in air at temperatures of at least about 550.degree.-600.degree. C. Water in small amounts also modifies the reaction to further reduce cracking although it also reduces the activity of the catalyst.
