    摘要: Compounds of the formula ##STR1## wherein R.sup.1 is C.sub.1-5 alkyl, R.sup.2 is selected from hydrogen and C.sub.1-5 alkyl, X is selected from hydrogen and --COR.sup.3 wherein R.sup.3 is selected from hydrogen and C.sub.1-6 alkyl are useful in room fresheners and other compositions for counteracting malodors in air, wherein the malodors are caused by one or more compounds selected from lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines. The defined compounds impart little or no fragrance to such compositions but the compositions may include additional fragrances. Particularly valuable and novel compounds are those wherein R.sup.1 is methyl, R.sup.2 is selected from hydrogen and methyl and X is --COR.sup.3 wherein R.sup.3 is C.sub.2-6 alkyl.
