Based on the catalytic addition of dimethylacetylenecarbinol to allyl halides with the participation of N -bromosuccinimide and molecular iodine, methods for the synthesis of simple 2-methyl-3-butyn-2-ol ethers of dihaloalkanols (chlorine, bromine and iodine derivatives) have been proposed. The resulting compounds were studied as antimicrobial additives for lubricating oils and fuels. The antimicrobial effectiveness of the studied compounds was determined by the zonal diffusion method using microorganisms: Pseudomonas aeruginosa, Mycobacterium phlei , Aspergillus niger, Penicillium chrysogenum , Cladosporium resinae . It was revealed that 2-methyl-3-butyn-2-ol ethers of dihaloalkanols with two iodine atoms significantly inhibit the growth of microorganisms at low concentrations. It has been established that iodoethers are 2-4.5 times more effective than ethanol. Unsaturated ethers do not decompose and cannot be corrosive; their use for these purposes does not cause side effects.
