Method of producing dimethyl sulphoxide Invention relates to production of dimethyl sulphoxide (DMSO) which is widely used in organic synthesis. According to the invention, dimethyl sulphide is oxidised with chlorine dioxide with molar ratio of sulphide to chlorine dioxide equal to 1:0.5 at temperature 7-10°C. The invention also describes preferable conditions for conducting the process. |

Use of n, n-diethylaniline as soman imitator in aqueous medium Imitator of a toxic chemical is an organophosphorus substance in aqueous media. The substance can be use to imitate contamination of water bodies when simulating the process of spreading of soman in fresh water rivers taking into account specific morphological features of separate parts of their channel and to determine the behaviour of spreading in time and degree of dilution of the contaminated region at a given distance from the source. |
