Welcome to Capital Butane!

The first Company to introduce a USA Made pharmaceutical grade N-Butane and N-Blend in aerosol cans!

Dedicated to innovation through our deep connection with hydrocarbon industry, CAPITAL BUTANE has once again defined the leaders of N-Butane and Butane blends.

Our "raw" n-butane is processed through multiple molecular sieves in tandem to remove impurities such as sulfur and moisture. Our molecular sieves are designed for and dedicated for high purity n-butane and other hydrocarbons. Freshly sieved n-butane is stored in dedicated finished hydrocarbon “pure” tanks. The product in all pure tanks is analyzed for odor, purity, olefins, sulfur and moisture at a minimum and must meet the specifications for a large range of customers, including pharmaceutical industries.
