Choose Environmentally Friendly Pesticide Intermediates

The general rule of the relationship between biodegradability and molecular structure is as follows: the linearity of the hydrophobic group is high and it is easy to degrade; the length of the hydrophobic chain has an effect on the degradability; The benzene sulfonate is easily degraded. For anionic emulsifiers, alkyl sulfate (AS) is the most degradable. Linear alkyl benzene sulfonate (LAS) is most easily degraded when the chain length is between C6 and C12. The alkyl chain is branched and its length is closer to the main chain, the more difficult it is to degrade. For non-ionic emulsifiers, short-chain alkyl groups, straight-chain alkyl groups, no phenolic groups in the molecule, PO and EO units are less prone to degradation, and EO chains of the same length are more degradable than PO chains.
