AbstractThe kinetics of the syntheses of N-alkyl, N,N-dialkyl, and N-(4-substituted phenyl) O-ethyl thioncarbamates from sodium ethyl xanthogenacetate, ten alkylamines, and eight substituted anilines were studied at 25, 30, 35, and 40 °C. The reactions were found to follow second-order kinetics. The kinetic (Arrhenius) parameters, such as the activation energy and the frequency factor, as well as the

Open-ended pores of a porous granule are filled with a liquid material which is at least partially immiscible with water, and sealed with a porous polyurea membrane which limits the release rate of the material into the surrounding medium. The membrane is formed by
(a) applying to the bare granule an organic solution comprising the liquid material and an organic polyisocyanate, followed by
(b) applying to the granule an aqueous solution comprising water and a catalytic amount of a catalyst selected from the group consisting of a basic organic tertiary amine and an alkyl tin carboxylate.
@ Disclosed herein is a method of controlling undesirable vegetation which comprises the application to the locus desired of a herbicidal composition comprising a herbicide selected from the group consisting of S-benzyl dipropylthiocarbamate, S-benzyl 2,5-dimethylpiperidine-1-carbothioate, S-benzyl methyl isopropyl thiocarbamate, S-benzyl propyl allyl thiocarbamate, S-benzyl ethyl cyclohexyl thiocarbamate, s-benzyl ethyl-sec-butyl thiocarbamate, S-(4-chlorobenzyl) dipropyl thiocarbamate, and S-benzyl isopropylsec-butyl thiocarbamate.
