Articles of 1-Methoxy-2-propyl acetate are included as well. (7) ESTER: The ester functional group has a similar character to the ketone and aldehyde functional group. They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen. Ex: isobutyl acetate contains an isobutyl functional group attached to an acetate group. Propyl acetate, also known as propyl ethanoate, is a chemical compound used as a solvent and an example of an ester. A carbonyl group is formed when an O atom and a C atom are joined by a double bond. It is an active solvent for nitrocellulose, cellulose acetate butyrate, polyester, alkyd, and acrylic resins. It is synthetically produced by having acetic acid and 1-propanol undergoing esterification reaction. The functional groups appear in alphabetical order in Tables 1-7. It derives from a propan-1-ol. The n-propyl acetate+ethanol and +2-propanol binary systems have an azeotropic point at 0.15 MPa. Propyl acetate, also known as 1-acetoxypropane or propyl ethanoate, belongs to the class of organic compounds known as carboxylic acid esters. In the example above, the right side of the ester as shown is a CH 3CH 2 3-Methyl Thio Propyl Acetate Halal, Kosher. . A carbonyl group is formed when an O atom and a C atom are joined by a double bond.
