With a total of 2 patents to his name, Bernard's work has implications in both agricultural and pharmaceutical applications.

Latest Patents

One of Bernard's latest patents is a process for the preparation of an alkyl 2-chloropropionate. This process involves the gradual contact of alkyl lactate with thionyl chloride in the presence of an organic base. The method ensures that there is an excess of thionyl chloride relative to the alkyl lactate, while maintaining a temperature below the decomposition point of the intermediate chlorosulphinate. This innovative approach allows for the production of alkyl 2-chloropropionates, which can be utilized in the manufacture of racemic or optically active 2-phenoxypropionic acids.

Another significant patent by Bernard is the process for the manufacture of aluminum monoethyl phosphite. This compound is particularly useful for protecting plants against fungal diseases. The process involves preparing a mixture of phosphite compounds, followed by saponification and neutralization with an inorganic base. The final step includes reacting the residual solution with a water-soluble aluminum salt, resulting in a product that can be effectively used in agricultural applications.
