Abstract
A process for making esters with bioresistant, fungal resistant and antimicrobial/antifungal properties with reduced color and improved yield. A fatty acid halide, preferably a chloride, or a fatty acid anhydride is reacted with bromo-nitro-propandiol (BNPD) to form an almost clear ester that can be used in commercial applications like metal working fluids where it is desired to prevent degradation by bio-organisms.
Claims23
A process for making a bio-resistant ester comprising the steps of:
- (a) adding around 1-2 molar equivalents of a fatty acid halide to a vessel;
- (b) adding around 1 molar equivalent of BNPD;
- (c) adding a sufficient amount of heat to initiate and sustain a reaction;
- (d) agitating said vessel
A process for making a bio-resistant ester comprising the steps of:
- (a) adding around 1-2 molar equivalents of a fatty acid anhydride to a vessel;
- (b) adding around 1 molar equivalent of BNPD;
- (c) adding a sufficient amount of heat to initiate and sustain a reaction;
- (d) agitating said vessel;
- (e) continuing said agitation and heat until the presence of alcohol groups has reached a minimum.
A process for making a bio-resistant ester comprising the steps of:
- (a) adding around 1-2 molar equivalents of a fatty acid chloride to a vessel:
- (b) adding around 1 molar equivalent of BNPD;
- (c) adding a sufficient amount of heat to initiate and sustain a reaction:
- (d) applying a vacuum to the reaction;
- (e) agitating said vessel;
- (f) removing HCl as it is produced;
- (g) adding a decolorizer after HCl ceases to be produced;
- (h) allowing a sufficient time to decolorize;
- (i) filtering out said decolorizer.
A process for making a bio-resistant ester comprising the steps of:
- (a) Adding around 1 molar equivalent of a nitro ester containing at least one hydrogen atom on the carbon bound to the nitrogen of the nitro group or near the carbon bound to the nitrogen of the nitro group.
- (b) Adding X2 gas under sufficient pressure, where X is a halogen and providing sufficient contact, via sparger, agitatation, or other method to add the halide to the carbon atom bound to the nitrogen of the nitro group or carbon atom near the carbon bound to the nitrogen of the nitro group.
A process for making a bio-resistant ester comprising the steps of:
- (a) Adding around 1 molar equivalent of a nitro ester containing at least one hydrogen atom on the carbon bound to the nitrogen of the nitro group or near the carbon bound to the nitrogen of the nitro group.
- (b) Adding Br2 gas under sufficient pressure and providing sufficient contact, via sparger, agitatation, or other method to add the bromine to the carbon atom bound to the nitrogen of the nitro group or carbon atom near the carbon bound to the nitrogen of the nitro group.
