New 1,3,-Dioxane derivs (I) (where R=lower alkyl; X = OR1, where R1 = H; a metal or ammonium cation; C1-18 alkyl, possibly substituted with halogen, O or S; alkenyl; acyloxalkyl; 5-alkyl-1,3-dioxane-5-yl-methyl; aryl, alkaryl or cycloalkyl, possibly substituted; or acyl, especially 5-alkyl-1,3,-dioxane -5-yl-carbonyl; or X = SR2, where R2 = C1-18 alkyl or aryl; or X = halogen, amino or substituted amino), may be prepared by condensation of trimethylolakanes and HCHO. |
