Abstract
Termite repellant treated cellulosic substrates and methods or producing the same.
Claims35
A composition comprising a treated cellulosic substrate wherein said treated cellulosic substrate comprises at least one quaternary ammonium compound having the formula:
- wherein Y is selected from H2BO3−;
- HBO3−2;
- BO3−3;
- B4O7−2;
- HB4O7−;
- B3O5−;
- B5O8−2;
- and BO2−;
- R1, R2, R3 and R4 are selected from i) substituted or unsubstituted alkyl groups or ii) substituted or unsubstituted alkenyl groups, wherein if i) or ii) is substituted, they have one or more substituent groups selected from aryl, heterocyclyl, hydroxyl, ester, benzyl, carboxyl, halo, nitro, cyano, alkoxy or oxo groups;
- and m is 1, 2, or 3, depending on the selection of Y, and wherein said treated cellulosic substrate is termite repellant.
The composition according to 25 wherein R1 and R2 of said third quaternary ammonium compound is independently chosen from alkyl groups having in the range of from 1 to 3 carbon atoms and R3 of said third quaternary ammonium compound has a different number of carbons than R4 of said third quaternary ammonium compound.
A method of repelling termites comprising:
- a) treating a cellulosic substrate with a solution comprising in the range of from about 1 to about 10 wt. % of at least one quaternary ammonium compound having the formula:
- thereby producing a treated cellulosic substrate,
- wherein said solution is metal coupler free;
- said treated cellulosic substrate is termite repellant;
- Y is selected from H2BO3−;
- HBO3−2;
- BO3−3;
- B4O7−2;
- HB4O7−;
- B3O5−;
- B5O8−2;
- and BO2−;
- R1, R2, R3 and R4 are selected from i) substituted or unsubstituted alkyl groups or ii) substituted or unsubstituted alkenyl groups, wherein if i) or ii) is substituted, they have one or more substituent groups selected from aryl, heterocyclyl, hydroxyl, ester, benzyl, carboxyl, halo, nitro, cyano, alkoxy or oxo groups;
- and m is 1, 2, or 3, depending on the selection of Y.
