    • A S-(-N-alkoxycarbonyl, N-substituted)amino methyl isothiourea derivative of the formula:
      wherein, each of R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which may be the same or different, represents an alkyl group, an alkenyl group, an alkynyl group, a haloalkynyl group, a haloalkenyl group, a haloalkylnyl group, an alkoxyalkyl group, a cycloalkyl group, a cycloalkenyl group, an aryl 'group, a substituted-aryl group, an aralkyl group, a substituted-aralkyl group, a naphtyl, a pyridyl,
      (wherein each of X', X 2 and X 3 , which may be the same or different, represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, an acetyl, a haloalkyl group, a halogen atom, CF 3 , N0 2 , hydroxy, a benzyl, phenyl, a phenoxy or phenylthio group) or
      (wherein each of Y 1 and Y 2 , which may be the same or different, represents a hydrogen atom, a lowered alkyl group, a halogen atom, CF 3 , a lowered alkoxy group, W represents a
      group, {in which each of R 7 and R 8 represents a hydrogen atom or a lowered alkyl group}, -0-group. a
      or a -OCH 2 - group, and m represents an integer of 0 to 2), and each of R 2 , R 3 , R 4 , R 5 and R 6 may be a hydrogen atom. And R4 and R 5 , or R 6 forms together with -(CH 2 ) n - (wherein n is an integer of 2 to 4), -CH 2 -0-CH 2 - or -CH 2 -S-CH 2 - ; provided, however, that at least one of R 4 , R 5 and R 6 is a hydrogen atom, is disclosed. This is a useful intermediate for the production of 1,3,5-thiadiazine-4-one derivatives.

    • Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine derivative of the formula: wherein R14 is a C1-C24 straight chain or branched alkyl group; or a C6-C24 aryl or arylalkyl group; R15 is a C1-C6 alkyl or a C6-C30 aryl or alkylaryl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid (WSF) formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing dithiazine or dithiazine derivative and a corrosion inhibiting formulation may be used to inhibit corrosion in the well.
