Usage

Description

MPMC, also known as Xylylcarb, is a colorless solid with limited solubility in water and fair solubility in acetonitrile, cyclohexane, and xylene. It is a non-systemic insecticide commonly used in agriculture to control various pests.

Uses

Used in Agriculture:
MPMC is used as an insecticide for controlling hoppers and other sucking pests on rice, as well as leafhoppers, planthoppers, and scale insects on fruit. Its non-systemic nature allows for targeted pest control without affecting the overall plant system, making it a valuable tool in integrated pest management strategies.

Metabolic pathway

In plants and animals, the principal pathways of xylylcarb metabolism are oxidation of the 4-methyl substituent, hydroxylation of the N-methyl group, hydrolysis of the carbamate ester to form phenols and conjugation.

Degradation

Xylylcarb is hydrolysed in alkaline conditions (PM).

The compounds represented by the general formula (I) can be synthesized by the methods disclosed in the specification.

Process for the production of N-methylcarbamates

Process for the production of N-methylcarbamates: STR1 (wherein RO- is the radical of a substituted phenol or of a naphthol), wherein: in a first reaction step methylamine and diphenyl carbonate are reacted with each other, operating in the liquid phase and as a continuous process, in order to form phenol and phenyl-N-methylurethane; in a second reaction step phenyl-N-methylurethane, within the related reaction mixture outcoming from the first step, is thermally continuously decomposed, to yield a gaseous stream containing methyl isocyanate, from which the components different than methyl isocyanate are condensed off; in a third step the methyl isocyanate stream, outcoming from the second step, after an optional preliminary condensation, is continuously fed and contacted with a solution of a substituted phenol or of a naphthol in an inert organic solvent, containing a basic catalyst, to form N-methylcarbamate (I); N-methylcarbamate (I) is finally recovered from the reaction mixture outcoming from the third step.
