  • Patent number: 4671815
    Abstract: This invention relates to salts of oxyalkylated amino compounds which render normally water insoluble components such as biocides, soluble in water and thereby improving their usefulness and effectiveness. These amino compounds render biocides such as methylene bis(thiocyanate) (MBT) and/or bis(trichloromethyl) sulfone (BTMS) water soluble. The soluble forms of these biocides afford more predictable, consistent and effective biocidal results when applied to systems contaminated with microorganisms such as bacteria, fungi, algae, molds, and certain yeasts and thus offer considerable advantages over insoluble, dispersible, emulsified forms of these biocides.

  • Patent number: 4579956
    Abstract: Amino-phosphonates are prepared by reacting an enamine with a phosphite ester, for example, according to the equation ##STR1## where OR' is an alcohol moiety and NR.sub.2 is an amino moiety, both R and R' being preferably hydrocarbon such as alkyl or R.sub.2 is part of a ring structure. These compounds have many uses, for example, as corrosion inhibitors, scale inhibitors, fuel stabilizers, etc. In addition, amino-phosphonates can be converted to alpha, beta - unsaturated phosphonates according to the equation ##STR2## which are useful in forming flame retardant polymers and copolymers.
