Claims8
The method of preparing a product 2-morpholone which comprises
- maintaining a reaction mixture containing as charge dialkanolamine ##STR5## wherein R is alkyl, cycloalkyl, alkaryl, aralkyl, aryl, alkenyl, alkynyl, or hydrogen and R' is alkyl, cycloalkyl, alkaryl, aralkyl, aryl, alkenyl, alkynyl, or hydrogen;
- adding to said reaction medium Gluconobacter or Acetobacter bacteria;
- maintaining said reaction mixture at ring-forming conditions thereby forming product 2-morpholone ##STR6## recovering said product 2-morpholone.
The method of preparing an N-substituted-2-morpholone which comprises
- maintaining a reaction mixture containing an N-substituted dialkanolamine ##STR7## wherein R is alkyl, cycloalkyl, alkaryl, aralkyl, aryl, alkenyl, alkynyl or hydrogen and R' is alkyl, cycloalkyl, alkaryl, aralkyl, aryl, or hydrogen;
- adding to said reaction medium bacteria selected from the group consisting of Gluconobacter oxydan ATCC #621 and Gluconobacter roseus IAM 1841;
- maintaining said reaction mixture at ring-forming conditions thereby forming product N-substituted-2-morpholone ##STR8## recovering said product N-substituted-2-morpholone.
