    Abstract: A process for the production of N-phosphonomethylglycine characterised in that it comprises:

    (a) reacting a 1,3.5-tricarboalkoxymethylhexahydro-1,3,5-triazine corresponding to the following general formula:
    wherein R represents an aliphatic or aromatic group; with an acyl chloride corresponding to the following general formula:
    wherein X represents chlorine, bromine or iodine; and R 1 represents an aliphatic or aromatic group; to form the N-carboalkoxymethyl-N-halomethyl amide of the acyl chloride corresponding to the following general formula:
    wherein X, R and R 1 are as defined above;
    (b) reacting the resulting amide with a phosphite corresponding to the following general formula:
    wherein R 2 and R 3 both represent aromatic groups or both represent aliphatic groups: and R 4 represents an aliphatic group or an aikati metal; to form a phosphonats compound corresponding to the following general formula;
    wherein R, R', R 2 and R 3 are as defined above; and
    (c) hydrolyzing the resulting phosphonate to yield N-phosphonomethylglycine is disciosed.

    The present invention provides advantages over the prior art.

    Abstract: Herbicidally active thiolcarbamates are employed in combination with certain allyl amine salts of thiocarbamic acid compounds having the formula
    wherein

    R 4 and R 5 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to about 6 carbon atoms;
    R 6 and R 7 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to 6 carbon atoms; and
    X is oxygen or sulfur wherein at least one of R 4 and R 5 and at least one of R 6 and R 7 is an allyl group. In a typical application, the allyl amine salt of thiocarbamic acid compound is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering single application of the herbicide effective over a longer period of time.
