Process for preparing anthraquinone

A container having a dual-neck configuration providing inner and outer seals for reactive or volatile materials stored therein. An inner cylindrical neck provides the inner seal, and is surrounded by an outer neck providing the outer seal. Inner and outer caps are threaded onto the respective inner and outer necks, and each cap is provided with an elastomeric liner. The inner cap is further provided with an axial bore to allow a hollow needle to pass therethrough, thereby enabling material within the container to be withdrawn through the needle, and the inner elastomeric seal reseals itself after withdrawal of the needle.
