일반 설명

Tetrafluoroboric acid is used as a catalyst for the protection and deprotection reactions of various carbohydrates. It participates in the synthesis of 4-sulfonic acid phenyl diazonium tetrafluoroborate, which was required for the preparation of sulfonated graphene (SG).

애플리케이션

Tetrafluoroboric acid solution may be used as a catalyst for the hydration of aromatic haloalkynes to α-halomethyl ketones in the absence of metal catalysts. It may also be used the epoxidized soybean oil (ESBO) ring opening step of fatty acids preparation.
