Purified acetylated derivatives of castor oil and compositions including same
View Patent ↗The present disclosure is directed to a single phase acetylated castor component (SP-ACC). An acetylated castor component is purified to produce the SP-ACC which contains a reduced amount of, or no, insoluble component(s) therein. The SP-ACC enhances the performance and properties of plasticizers of which it is a component.
1. A single phase acetylated castor component having less than about 0.2 wt % insoluble components after exposure to 15° C. for at least one week, wherein the component has an iodine number of less than 40 g I 2 /100 g.
2. The component of claim 1 wherein the single phase acetylated castor component is selected from the group consisting of a single phase acetylated castor oil, a single phase acetylated castor wax, and combinations thereof.
3. The component of claim 1 having a hydroxyl number from 0 to less than 5 as measured in accordance with DIN 53402.
4. The component of claim 1 having a viscosity less than 2000 mPa·s as measured in accordance with ASTM D 445 at 25° C.
5. The component of claim 1 having a turbidity from 1.0 NTU to 50 NTU.
6. The component of claim 1 having color less than 500 APHA.
7. A composition comprising:
the single phase acetylated castor component of claim 1 ;
an epoxidized fatty acid ester; and
the composition has less than 0.2 wt % insoluble components after exposure to 15° C. for at least one week.
8. The composition of claim 7 wherein the epoxidized fatty acid ester is selected from the group consisting of epoxidized soybean oil, epoxidized propylene glycol dioleate, epoxidized palm oil, epoxidized linseed oil, epoxidized fatty acid methyl esters, epoxidized derivatives of each of the foregoing, and combinations thereof.
9. A polymeric composition comprising:
a polymeric resin;
a plasticizer composition comprising the single phase acetylated castor component of claim 1 and optionally an epoxidized fatty acid ester; and
the polymeric composition has a loop spew value from 0-2 as measured in accordance with ASTM D 3291.
10. The polymeric composition of claim 9 wherein the plasticizer composition comprises less than 0.2 wt % insoluble components after exposure to 15° C. for at least one week.
11. The polymeric composition of claim 9 wherein the plasticizer composition comprises an epoxidized fatty acid ester selected from the group consisting of epoxidized soybean oil, epoxidized propylene glycol dioleate, epoxidized palm oil, epoxidized linseed oil, epoxidized fatty acid methyl esters, epoxidized derivatives of each of the foregoing, and combinations thereof.
12. A coated conductor comprising:
a metal conductor; and
a coating on the metal conductor, the coating comprising a polymeric resin and a plasticizer composition comprising the single phase acetylated castor component of claim 1 and optionally an epoxidized fatty acid ester.
13. The coated conductor of claim 12 wherein the plasticizer composition comprises less than 0.2 wt % insoluble components after exposure to 15° C. for at least one week.
14. The coated conductor of claim 12 wherein the plasticizer composition comprises an epoxidized fatty acid ester selected from the group consisting of epoxidized soybean oil, epoxidized propylene glycol dioleate, epoxidized palm oil, epoxidized linseed oil, epoxidized fatty acid methyl esters, epoxidized derivatives of each of the foregoing, and combinations thereof.
15. The component of claim 1 having an iodine number of less than or equal to 3 g I 2 /100 g.
