    • PURPOSE: A rot-preservative or fungicide that contains a trihaloacrylic acid derivative as an active ingredient, thus being effective against wood-destroying fungi and other fungi propagating on a variety of industrial materials such as woods, laminatings, paper, fiber, leather, adhesives or synthetic resins.
      CONSTITUTION: The objective rot-preservative or fungicidal agent contains a trihaloacrylic acid derivative of formulaI(X is Cl, Br, I; R is hydroxyl, alkoxy, alkyl, phenoxy, amino, alkylamino, phenylamino, formula II) as an active ingredient. The content is usually 0.01W95, preferably 0.5W78wt%. The compound of formulaIis prepared by allowing the addition product between a 3- halopropiolic acid of formula III andI
      2 to react with thionyl chloride, followed by reaction between the acid chloride and R'H (R' is R except hydroxyl). An example of formulaIis N-O-methylbenzyl 2,3,3-triiodoacrylamide.
