Application

1.It is mainly used as polymerization inhibitor, UV inhibitor, dye intermediate and antioxidant BHA for synthesis of edible oils and cosmetics.
2. It is used as polymerization inhibitor, UV inhibitor, dye intermediate and antioxidant BHA (3-tert-butyl-4-hydroxyanisole) for the synthesis of food oils and cosmetics.
3. Solvent. Used as an inhibitor of vinyl plastic monomer; Uv inhibitor; Dye intermediates and antioxidant BHA (3-tert-butyl-4-hydroxyanisole) used in the synthesis of edible oils and cosmetics. Its biggest advantage is that the monomer after adding MEHQ and other monomers do not need to be removed when copolymerizing, can be ternary direct copolymerization, also can be used as antioxidant, antioxidant and so on.
