Title:
【発明の名称】改良された酸化プロピレンとスチレン単量体の同時製造方法
Document Type and Number:
Japanese Patent JP3340068
Kind Code:
B2
Abstract:
The propylene oxide and styrene co-production process generates a heavy residue byproduct containing metals, mainly sodium, which previously was adequate for use only as low quality fuel. According to the invention, the heavy residue is dehydrated in the presence of a strong inorganic acid at temperatures of 150-250 DEG C and pressures below the atmospheric pressure to yield styrene and recover 2-phenylethanol, a compound used in the perfume industry, and a heavy residue substantially free of metals that may be used as fuel.
