    摘要: A composition which is capable of releasing acrolein and is easy to handle contains (i) an acetal of acrolein with a C.sub.1-6 alcohol with 1 to 4 hydroxyl groups and (ii) an acid soluble therein and chemically compatible with a pK.sub.s value of less than 4 and (iii) is anhydrous. A preferred composition contains 2-vinyl-1,3-dioxolane as acetal, anhydrous oxalic acid, fumaric acid or maleic acid or a mixture of mono- and di(C.sub.1 - to C.sub.3 -)alkyl phosphate as acid and, in addition, a non-ionic surfactant. The acrolein is released at the site of use upon contact with for example water for the purpose of combatting microbial, vegetable and animal pests.
