US Patent:

48702048, Sep 26, 1989
Filed:

Sep 17, 1987
Appl. No.:

7/098328
Inventors:

Ezekiel H. Hull - Greensboro NC
Edward P. Frappier - Kernersville NC
Assignee:

Morflex Chemical Company, Inc. - Greensboro NC
International Classification:

C07C 67313
US Classification:

560180
Abstract:

Citrate esters are formed utilizing organic titanates as a catalyst allowing excess alcohol to be removed. Four citrate esters have been found which provide advantageous plasticizing properties to PVC compositions which include superior toxicity test results and superior soapy water extraction test results. The four citrate esters are: acetyltri-n-hexyl citrate, n-butylryltri-n-hexyl citrate, acetyltri-n-(hexyl/octyl/decyl) citrate, and acetyltri-n-(octyl/decyl) citrate. Articles formed from the PVC plasticized mixtures are extremely useful in the medical or health care field as they demonstrate a low order of toxicity.
