Abstract
Silanized antimicrobial compounds are disclosed which are the reaction products of chlorinated phenols, bis-phenols, dihydric phenols, hydroxy diphenyl ethers and ortho or para hydroxybenzoic acids and their lower alkyl esters with an amino substituted silane having the general formula NH.sub.2 (CH.sub.2).sub.3 Si(R).sub.3 wherein R is methoxy, ethoxy or propoxy and n is 2, 3, or 4. The silane moiety is joined to the antimicrobial compound through the oxygen of a hydroxyl group of the starting compound.
Claims26

- R.sub.1 and R.sub.2 are methoxy, ethoxy or propoxy;
- and n is 2 to 4.
An antimicrobial silanized compound having the formula ##SPC16##
- wherein R.sub.1 and R.sub.2 are methoxy, ethoxy or propoxy, and n is 2 to 4.
An antimicrobial silanized compound having the formula ##SPC17##
- wherein R.sub.1 and R.sub.2 are methoxy, ethoxy or propoxy and n is 2 to 4.
An antimicrobial silanized compound being the reaction product of
- NH.sub.2 (CH.sub.2).sub.n Si(R).sub.3
- wherein R is methoxy, ethoxy or propoxy and n is 2 to 4, combined with a reacting compound taken from the group consisting of chlorinated phenols, bis-phenols and diphenyl ethers;
- 6 to 9 carbon atom alkyl or chlorine-substituted dihydric phenols;
