Lanzhou Ruilong High-tech New Materials Co., Ltd. is located in the Lanzhou New Area of Gansu Province. It primarily produces products such as 2-ethylanthraquinone and 2-amylanthraquinone. Established in October 2021, the company covers an area of 100,000 m2 with a building area of 28,500 m2. It employs over 200 staff and possesses a large number of advanced production equipment, along with a significant pool of management and technical talent.

The company is equipped with comprehensive basic testing capabilities and strong product development strength, ensuring product quality and the development of new products. It strictly operates in accordance with the ISO9001 Quality Management System, ISO14001 Environmental Management System, and OHSAS Occupational Health and Safety Management System. Safety production, environmental protection, and energy conservation are treated as the fundamental elements of enterprise development, and product quality is regarded as the lifeblood of the company.

2-Ethylanthraquinone (2-EAQ) is an important organic synthesis intermediate widely used in the production of hydrogen peroxide, vat dyes, disperse dyes, reactive dyes, and more. Currently, large-scale hydrogen peroxide manufacturers both domestically and internationally use the anthraquinone method to produce hydrogen peroxide. The output and quality of 2-ethylanthraquinone significantly impact the production of hydrogen peroxide and the development of related industries.

2-Amylanthraquinone is an upgraded auxiliary agent for hydrogen peroxide production, greatly enhancing production efficiency. As early as the 1990s, foreign countries began using 2-amylanthraquinone to produce high-concentration, high-quality hydrogen peroxide. In China, due to constraints in the supply of 2-amylanthraquinone and its application technology, production has remained reliant on the 2-ethylanthraquinone method, resulting in low-content, high-energy-consumption hydrogen peroxide. The low solubility of 2-ethylanthraquinone causes it to easily precipitate in pipelines, disrupting normal production, while excessively high hydrogenation efficiency increases the degree of anthraquinone degradation, leading to higher raw material consumption. Compared to 2-ethylanthraquinone, 2-amylanthraquinone offers higher solubility and is less prone to degradation under high hydrogenation efficiency. Therefore, its use in working fluid significantly improves hydrogenation efficiency, thereby increasing plant capacity (by 50% to 100%, depending on the plant conditions), enhancing plant safety, reducing consumption, and enabling the production of hydrogen peroxide that meets electronic-grade standards.

With the growing demand for caprolactam and propylene oxide (both requiring high-concentration hydrogen peroxide produced via the amylanthraquinone method), China has successfully developed and applied technology for producing hydrogen peroxide using the 2-amylanthraquinone method. Our products are already in use by numerous hydrogen peroxide manufacturers, with remarkable results.
