Dioctyl terephthalate (DOTP) is an organic compound with molecular formula C24H38O4. It is a transparent oily liquid, insoluble in water and soluble in general organic solvents [1]. Dioctyl terephthalate is a main Plasticizer with excellent performance for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, volatile resistance, extraction resistance, softness and good electrical insulation performance, and shows excellent durability, soapy water resistance and low softness in products.

Recently, Nanning Base of Yuchai Engineering Research Institute officially settled in Nanning Hi-tech Zone, the capital of Guangxi. The construction of this base project is Yuchai’s another major work on building a corporate technology R&D core platform after upgrading the enterprise technology center to the Engineering Research Institute in 2007. It is also Yuchai’s efforts to build a large multinational enterprise group with international competitiveness and improve. Major initiatives in product core competitiveness.
The Yuchai Engineering Research Institute was established in July 2007. It has a state-level enterprise technology center and a nationally accredited laboratory. It is a research center for Guangxi Internal-combustion Engine Engineering, a small diesel high-tech talents post and a post-doctoral research station. During the “Ninth Five-Year Plan†and “Tenth Five-Year Plan†periods, Yuchai has repeatedly undertaken national scientific and technological research projects.
The Nanning base that was settled in this project is located at Gaoxin Dongsan Road, High-tech Zone, Nanning. The preliminary planning covers an area of ​​120 mu and a total investment of RMB 310 million. The project construction is divided into six functional areas with a total construction area of ​​nearly 70,000 square meters. After the base is completed, it will have an R&D building, a product showroom and a multi-functional conference hall as well as a pilot trial plant, an outdoor testing ground (runway) and supporting ancillary facilities for engineering research institutes, and meet the standards of the national enterprise technology center in the planning and layout. At the comprehensive level, “the first-class in China and the top five in the world†(first-class environment, first-rate facilities, first-rate talent, and first-class research and development level) will greatly enhance Yuchai’s ability to independently innovate, enhance overall technology, and lead China’s engine manufacturing industry to the world. .
The person in charge of the Yuchai Group stated that Yuchai’s selection of a new R&D base in Nanning with a wider R&D scope, larger scale, and more complete supporting facilities is based on Nanning’s location advantage, comprehensive environmental advantages, and industrial policy advantages. It will be conducive to attracting international-level R&D personnel, strengthening international technical exchanges and cooperation, and laying a solid foundation for Yuchai to develop into an international large-scale enterprise group in the future.
Dioctyl terephthalate (DOTP) is a main plasticizer with excellent performance for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, volatile resistance, extraction resistance, softness and good electrical insulation performance, and shows excellent durability, soapy water resistance and low softness in products. Because of its low volatility, the use of DOTP can fully meet the temperature resistance requirements of wires and cables, and can be widely used in 70 ° C resistant cable materials (IEC standard) and other PVC soft products. DOTP can also be used in the production of artificial leather film in addition to a large number of plasticizers for cable materials and PVC. In addition, it has excellent phase solubility and can also be used as plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. It can also be used as plasticizer of synthetic rubber, coating additive, precision instrument lubricant, lubricant additive, and also as softener of paper.
