Claims10
A compound which is a di- and/or a tristyrylphenol monoglycidyl ether adduct of the compound of Formula I:
- A compound which is a di- and/or a tristyrylphenol monoglycidyl ether adduct of the compound of Formula I:
- where m is from 1 to 60;
- wherein the di- and/or a tristyrylphenol monoglycidyl ether adduct of the compound of Formula I is formed by the reaction of the compound of Formula I and the compound of Formula II:
- where each R is independently F, Cl, Br, CN, C1-C6-alkyl, or C1-C6-alkoxy;
- R1 is H or 1-phenylethyl;
- and each n is independently 0, 1, 2, or 3.
A method comprising the step of contacting a maltodextrin with a di- and/or a tristyrylphenol monoglycidyl ether in the presence of a Lewis acid under conditions sufficient to produce a di- and/or a tristyrylphenol monoglycidyl ether adduct of the maltodextrin, wherein the maltodextrin is represented by Formula I:
- where m is from 1 to 60;
- and the di- and/or the tristyrylphenol monoglycidyl ether is represented by Formula II:
- where each R is independently F, Cl, Br, CN, C1-C6-alkyl, or C1-C6-alkoxy;
- R1 is H or 1-phenylethyl;
- and each n is independently 0, 1, 2, or 3.
