Claims
- 1. A composition comprising, a compound represented by formula (I):R—O[(EO)x(PO)y](EO)z—H (I) wherein EO is an oxyethylene group; PO is an oxypropylene group; R is a, straight-chain or branched alkyl group or alkenyl group having 6 to 30 carbon atoms; x is a value of 1 to 30 on the average; y is a value of 1 to 30 on the average; z is a value of 1 to 30 on the average; and the copolymer —[(EO)x(PO)y]— may be a random copolymer or a block copolymer; and a technical grade of an active ingredient or an active compound for an agricultural chemical.
- 2. The composition according to claim 4, further comprising a surfactant other than the compound represented by formula II).
- 3. The composition according to claim 4, further comprising a chelating agent.
- 4. The composition according to claim 1, wherein the weight ratio of the compound represented by formula (I) to technical grade of active ingredient or active compound for an agricultural chemical is 0.03 to 50.
- 5. The composition according to claim 1, wherein the weight ratio of the compound represented by formula (I) to technical grade of active ingredient or active compound for an agricultural chemical is 0.04 to 20.
- 6. The composition according to claim 1, wherein the weight ratio of the compound represented by formula (I) to technical grade of active ingredient or active compound for an agricultural chemical is 0.1 to 10.
- 7. A method of preparing the compound represented by formula (I) in claim 4, the compound represent by formula (I) is obtained by first adding ethylene oxide and propylene oxide to an alcohol having the formula R—OH to obtain R—O[(EO)x(PO)y]—H and then adding ethylene oxide thereto.
- 8. A method of preparing the compound represented by formula (I) in claim 4, the compound represented by formula (I) is obtained by first adding ethylene oxide to an alcohol having the formula R—OH to obtain R—O—(EO)x—H, then adding propylene oxide to obtain R—O[(EO)x(PO)y]—H and finally, adding ethylene oxide thereto.
- 9. A method for enhancing the effect of an agricultural chemical which comprises the step of feeding a compound represented by the general formula (I) together with the agricultural chemical to a site where the effect of the agricultural chemical is required:R—O[(EO)x(PO)y](EO)z—H (I) wherein EO is an oxyethylene group; PO is an oxypropylene group; R is a straight-chain or branched alkyl group or alkenyl group having 6 to 30 carbon atoms; x is a value of 1 to 30 on the average; y is a value of 1 to 30 on the average; and z is a value of 1 to 30 on the average.
- 10. The method according to claim 1 wherein a surfactant other than the compound represented by the formula (I) is also further fed.
- 11. The method according to claim 1 wherein one or more of the compounds described in claim 1 and 0.01 to 30 mols of a chelating agent per mol of the compound are also fed.
- 12. The method according to claim 1, wherein the copolymer —[(EO)x(PO)y]— of the compound represented by formula (I) is a block copolymer.
