Recently, the aldehyde-based chemical products project invested and built by Qixiang Tengda, a subsidiary of Shandong Energy Group’s New Materials Company, was successfully completed and entered the trial operation phase. Two high-end fragrance products, namely new jasmonal and anisylpropanal, were produced successfully, filling a gap in China’s market. It is reported that aldehyde-based fragrances such as neonyl acetal and anisaldehyde propional are high-end fragrances widely used, capable of being employed in the blending of almost all floral scents. It is used in formulating various premium perfumes, cosmetics, deodorants, liquid detergents, and soap fragrances, with a maximum usage level of 10%. The production of high-end fragrances such as neosantal aldehyde and anisylpropanal relies on traditional propanal condensation and hydrogenation processes, which require precious metal catalysts and involve hazardous hydrogenation steps. At present, there is no large-scale production capacity in the country; only a few manufacturers carry out small-scale production or pilot tests, with over 90% of the products relying on imports. In order to actively respond to the requirements of \"extending, supplementing, and strengthening industrial chains\" as well as \"driving high-quality development through innovation,\" and based on market research and an assessment of the future trends in the industry, Qixiang Tengda plans to develop high-value fine chemical products building on its existing product portfolio. This move will enable the company to enter the field of high-end synthetic fragrances, thus providing a solid foundation for optimizing its product structure and expanding its business in high-value areas. Upon receiving the research and development task, the team members began working day and night to tackle the challenges involved. After conducting hundreds of sets of experiments, all experimental development was essentially completed by July 2025; the entire experimental process was finalized, a qualified product was produced, and preliminary approaches to the manufacturing process were established. From July to September, experimental optimization and exploration of relevant boundary conditions were completed. With limited time and heavy tasks, the progress of project construction determines the timing of bringing the product to the market. Since it is a completely new, in-house developed project, the materials involved in the process from the laboratory to the industrial installation are extremely numerous. The pressure during the entire design process is no less than that during the experimental development phase. From scratch, the entire process package and construction drawings were completed by the end of December 2025. On February 9, 2026, the aldehyde production unit of Qixiang Tengda officially began its commissioning process, marking the start of its trial operation. During the trial operation phase, the employees of Qixiang Tengda worked together with unity and determination to overcome various challenges ； All units and departments worked closely together in a coordinated manner, creating a strong collective effort to ensure that the entire driving process proceeded safely, smoothly, and in an orderly fashion. After 5 consecutive days and nights of relentless effort, the aldehyde unit remained in stable operation; all process parameters gradually reached the design specifications, and all indicators met the production requirements. On February 13, 2026, the facility successfully produced qualified products, achieving the set goal of a successful first operation. It was able to start producing two high-end fragrance compounds: new jasmonal and anisaldehyde, thus delivering outstanding results through hard work and commitment. The aldehyde-based chemical series project developed by Qixiang Tengda is an independent innovation of the company. It features advantages such as a short production process and mild reaction conditions. Compared with foreign condensation-hydrogenation processes, the technology developed by Qixiang Tengda does not involve hazardous procedures and operates under milder conditions; its average yield is 5% to 10% higher than that of traditional processes, offering significant competitiveness in terms of process safety and production costs. The independent supply of these two high-end aldehyde-based fragrances has not only successfully filled the technical gaps in related fields in China, but also, thanks to the advantages of local production, enabled rapid response to the diverse fragrance formulation needs of downstream industries, thereby enhancing China’s influence within the fragrance industry chain. In the future, Qixiang Tengda will continue to build on the advantages of industrial chain collaboration to move forward steadily on the path of high-quality development.
