Esters with antimicrobial, bioresistant and fungal resistant properties

Abstract

A bromine/nitro moiety linked into the backbone of an ester or other compound over a wide range of occurrence rates provides antimicrobial, bio-resistant and fungal resistant properties for metal working fluids (MWF)s and other coatings. The moiety can be have the bromo and nitro groups linked to the same or different carbon atoms. The present invention also relates to urethanes, urea, amides, imides, carbonates, ethers, siloxanes, and many other types of linkages essential to MWF bases.

I claim: 
     
         1 . A molecule of the following structure: 
       
         
           
           
               
               
           
         
         where R and R′ are equal or not equal and are saturated or unsaturated, linear or branched alkyl from 5-22 carbons, polysiloxane or polydimethylsiloxane with molecular weights up to 2000, where A is selected from the group consisting of linear or branched, saturated or unsaturated, alkyl, alkynal with from 1-22 carbons, or —Br. 
       
     
     
         2 . The molecule of  claim 1  where R═R′═—(CH 2 ) 7 CH 3  and A═—Br. 
     
     
         3 . A metal working fluid base comprising a molecule according to  claim 1 . 
     
     
         4 . A surfactant comprising a molecule according to  claim 1 . 
     
     
         5 . A foaming or anti-foaming agent comprising a molecule according to  claim 1 .
