TWO-STAGE METHOD OF OBTAINING 1,3,5-TRIMETHYLHEXAHYDRO-1,3,5-TRIAZIN CONCENTRATE Russian patent published in 2015 - IPC C07D251/04 

Abstract RU 2571086 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method for obtaining 1,3,5-trimethylhexahydro-1,3,5-triazine with concentration 63-69%, which has freezing temperature to -45°C, consisting of two stages of synthesis. At the first stage 1,3,5-trimethylhexahydro-1,3,5-triazine with concentration 45-50% is obtained, at the second stage interaction of gaseous methylamine with paraformaldehyde, which is present in mixture with 1,3,5-trimethylhexahydro-1,3,5-triazine, obtained at the 1-st stage, takes place.

EFFECT: obtaining compound, possessing high efficiency of extraction hydrogen sulphide from mazuts and water-crude oil mixtures, which does not contain residual quantity of formaldehyde.
