Abstract
Disclosed is a wood preservative composition comprising creosote and/or pentachlorophenol (PCP) and one or more unsaturated fatty esters. The composition is useful for reducing insect and microbial decay in wood. Further disclosed are methods of making and using such a composition and wood treated with such a composition.
Claims26
A composition comprising:
- i) at least about 85 wt. % creosote;
- and
- ii) at least about 3 wt. % of a fatty ester component, which comprises greater than 90 wt. % of one or more C1-C6 alkyl esters of C10-C50 unsaturated fatty acids;
- and
- iii) at least about 1 wt. % of an ester of boric acid;
- wherein the composition contains less than 2 wt. % water and is a substantially homogenous solution at a temperature of about 15° C. to about 35° C. for up to one month.
3 more elements
A composition comprising:
- i) about 1 to 20 wt % pentachlorophenol;
- ii) about 65 to 98 wt % diesel;
- iii) about 1 to 15 wt % of one or more C1-C6 alkyl esters of C10-C50 unsaturated fatty acids;
- and
- iv) an ester of boric acid;
- wherein the composition contains less than 2 wt. % water.
3 more elements
A composition comprising:
- i) about 1 to 20 wt. % pentachlorophenol;
- ii) at least about 65 wt. % diesel;
- and
- iii) a fatty ester component, which comprises one or more C1-C6 alkyl esters of C10-C50 unsaturated fatty acids;
- and
- iv) boric acid ester;
- wherein the composition is a substantially homogenous solution at a temperature of about 15° C. to about 35° C. for up to one month;
- and the composition contains less than 2 wt. % water and no more than 0.25 wt. % suspended solids.
5 more elements
A composition comprising:
- i) about 3 to 15 wt. % pentachlorophenol;
- ii) at least about 65 wt. % diesel;
- and
- iii) about 1 to 15 wt. % of one or more C1-C6 alkyl esters of C10-C50 unsaturated fatty acids;
- and
- iv) about 1 to 5 wt. % of a borate compound, which comprises (a) monoethanolamine ester of boric acid and (b) boric acid and/or disodium octaborate tetrahydrate;
- wherein the composition contains less than 2 wt. % water and is a substantially homogenous solution at a temperature of about 15° C. to about 35° C. for up to one month;
- and the amount of naphthalene emitted into the atmosphere by the composition as measured by head space analysis at 70° C. is less than 20 μg/m3.
