  • Patent number: 4783531
    Abstract: In the production of an S-substituted isothiourea including the functional group ##STR1## in which R.sup.1 is an alkyl, alkenyl, aryl or aralkyl radical, wherein a thiourea including the functional group ##STR2## is reacted with an etherifying agent to replace H by R.sup.1, the improvement which comprises effecting the reaction in two steps, in the first step reacting the thiourea material with an etherifying agent including the radical Rin whichR is an alkyl, alkenyl aryl or aralkyl radical different from R.sup.1thereby to produce the ether ##STR3## and in the second step reacting the ether with a compound of the formula R.sup.1 SH. The process is particularly applicable to the production of the known herbicide ##STR4## from the corresponding thiourea where in the first step methyl bromide or methyl iodide is used to form the S-methyl isothiourea which is then interchanged with ethyl mercaptan. Higher overall yields and/or economies are thereby achieved.

  • Patent number: 4725684
    Abstract: A process for producing urea cyanurate which comprises reacting an aqueous solution of urea with cyanuric acid at a temperature below the melting point of urea provides reaction conditions which minimize urea decomposition and are energy efficient. The urea cyanurate product can be used directly in the manufacture of cyanuric acid in a process which minimizes the build up of scale on the reactor walls. The cyanuric acid product has reduced concentrations of by-products such as ammelide and ammeline.

  • Patent number: 4518761
    Abstract: The present invention is directed to a new process for the preparation of mixed trimers by at least partly trimerizing the isocyanate groups of at least two organic isocyanates of a reactivity which differs in the sense of the trimerization reaction, in the presence of trimerization catalysts and optionally interrupting the trimerization reaction at the respectively desired degree of trimerization, in which process the less reactive isocyanate component is introduced, polymerization is then commenced in the presence of the catalyst with the trimerization of at least 0.1% of the isocyanate groups and the more reactive isocyanate component is finally metered into the reaction mixture thus obtained; the mixed trimers obtained according to this process; and the use of the mixed trimers having free isocyanate groups obtained by this process, optionally in a form blocked by blocking agents for organic polyisocyanates, as a starting material for the production of polyurethane plastics materials.
