## Abstract

Epoxidized glyceride acetates are made by a process which comprises reacting an epoxy fatty acid ester and triacetin.

## Claims

### Claim 1

A process for the production of an epoxidized glyceride acetate which comprises reacting an epoxy fatty acid ester and triacetin.

### Claim 2 (depends on 1)

The process of claim 1 wherein the epoxy fatty acid ester is a triester of a fatty acid and glycerol wherein the fatty acid components of the triester are derived from C3-24, fatty acids, with the proviso that at least 80% oft. fatty add units of the triesters contain at least one C═C double band and with the additional proviso that at least one C═C double bond per molecule of triester is present in epoxidized form.

### Claim 3 (depends on 1)

The process of claim 1 wherein the process is carried oat in the presence of a transesterification catalyst.

### Claim 4 (depends on 3)

The process of claim 3 wherein the catalyst is used in a quantity of from 0.01 to 1.0% by weight, based on the total quantity of epoxy fatty acid ester used and triacetin.

### Claim 5 (depends on 1)

The process of claim 1 wherein the process is carried out at a temperature of from 120 to 240° C.

### Claim 6 (depends on 1)

The process of claim 1 wherein the process is carried out in a time period of from 1 to 6 hours.

### Claim 7 (depends on 1)

The process of claim 1 wherein the mole ratio of epoxy fatty acid ester to triacetin is from 1:2 to 2:1.

### Claim 8

A process for the production of a product comprising a major amount of an epoxidized diglyceride acetate which comprises reacting an epoxy fatty acid ester and triacetin wherein the molar ratios of epoxy fatty acid esters to triacetin is from 1:2 to 2:1.

### Claim 9 (depends on 8)

A method of plasticizing a halogen-containing plastics comprising adding to a halogen-containing plastic a plasticizing-effective amount of a compound of claim 8.
