Sivureaktiot, known in English as side reactions, are unintended chemical transformations that occur alongside the desired reaction in a chemical process. These reactions often compete with the main reaction, consuming reactants and potentially forming unwanted byproducts. Understanding and controlling side reactions is crucial for optimizing chemical synthesis and industrial processes.

Several factors can influence the occurrence and extent of side reactions. These include reaction temperature, pressure, concentration of reactants, presence of impurities, and the choice of catalyst or solvent. For instance, higher temperatures can sometimes accelerate side reactions more than the main reaction, leading to lower yields of the desired product. Similarly, certain impurities might act as catalysts for unwanted pathways.

The consequences of side reactions can be significant. They can reduce the overall yield and purity of the target compound, making purification more challenging and costly. In some cases, side reactions can produce hazardous or environmentally detrimental substances. Identifying the specific side reactions occurring in a process often involves detailed analytical techniques such as chromatography and spectroscopy.

Strategies to minimize side reactions include careful control of reaction conditions, using highly pure starting materials, and selecting appropriate catalysts and solvents. Sometimes, the reaction pathway can be modified by altering the order of addition of reactants or by using protective groups to temporarily block reactive sites. In industrial settings, optimizing reaction parameters to suppress side reactions is a key aspect of process development and economic viability.
