Abstract

Compounds of the formula ##STR1## in which R is alkylene, vinylene, methylvinylene, phenylene, cyclohexenylene, 1,2-dichlorovinylene and ethylidene, R¹ and R² are alkyl and R³ is hydrogen or alkyl or their amine salts and their use in retarding the ripening of picked fruits, vegetables and other merchantable materials of plant origin.

Claims

1. The compound having the structural formula ##STR17## or a salt thereof wherein the anion is chloride, bromide, acetate, sulfate or phosphate.

2. A method for retarding the ripening of bananas comprising contacting said bananas with a compound having the structural formula ##STR18## in which R is alkylene having 1 to 4 carbon atoms, vinylene, 1,2-dihalo vinylene, 1-methyl vinylene, and ethylidene;

R¹ and R² are independently alkyl having 1 to 4 carbon atoms, and R³ is hydrogen or alkyl having 1 to 6 carbon atoms or a salt thereof wherein the anion is chloride, bromide, acetate, sulfate or phosphate.

3. A method of claim 2 wherein R is alkylene having 1 to 3 carbon atoms, vinylene, 1,2-dichlorovinylene, 1-methyl vinylene and ethylidene;

R¹ and R² are both methyl or both ethyl and R³ is hydrogen or alkyl having 1 to 2 carbon atoms.

4. A method of claim 2 wherein R is ethylene, R¹ is ethyl, R² is ethyl and R³ is hydrogen.

5. A method of claim 2 wherein R is 1,2-dichlorovinylene, R¹ is methyl, R² is methyl and R³ is hydrogen.

6. A method of claim 2 wherein R is 1-methyl vinylene, R¹ is methyl, R² is methyl and R³ is hydrogen.

7. A method of claim 2 wherein R is ethylene, R¹ is methyl, R² is methyl and R³ is methyl.
