The interaction of sodium hypochlorite as a component of wastewater production of caustic soda and chlorine compounds from olefinic C4-C7 number contained in wastewater olefinic production was investigated.

The processes of neutralization of sodium hypochlorite, which are implemented in the industry, are very energy-intensive or require large amounts of reagents. That is why it was suggested to intensify the interaction of sodium hypochlorite with olefins by using cavitation fields.

Based on the experimental results the main kinetic parameters of the process was calculated: the rate constant, order of reaction temperature coefficient. It is assumed that the process is carried out for a radical mechanism.

It was found out that as increasing temperature and power ultrasonic emitter rate constant of the reaction between sodium hypochlorite and olefins increases. In this case the duration of process and unit costs of energy for the decomposition of sodium hypochlorite was reduced.

The results will be used to develop energy-efficient process simultaneous neutralization of hypochloritic and olefinic wastewater generated in related industries.
