Abstract A number of N,N′‐diacylalkyldiamines were prepared from the reaction of acid chlorides with 1,8‐diaminooctane and 1,12‐diaminododecane and screened for anti‐rust properties and antimicrobial activity in spent coolants of water‐based cutting fluids. Aqueous solutions of N,N′‐dihexanoyl‐1,8‐diaminooctane and N,N′‐isobutyroyl‐1,12‐diaminododecane showed good anti‐rust properties for water‐based cutting fluids. Aqueous emulsions of N,N′‐dibutyroyl‐, dipentanoyl‐, dihexanoyl‐ and dioctanoyl‐1,12‐diaminododecane showed good lubricities and antimicrobial activity for water‐based cutting fluids.
