Read： 917 Time：5months ago Source：Transform the World with Simplicity

As a key raw material in the chemical industry, poly (terephthalic acid) (PTA) plays an indispensable role in the synthesis of polyester fibers and PET plastics. With the continuous growth of market demand, PTA production and testing technology is also constantly upgrading. This article will first introduce the detection method of PTA, in-depth discussion of the current mainstream analysis technology.

1. PTA detection method

traditional method

In the past, the detection of PTA mainly relied on traditional chemical analysis methods, such as infrared spectroscopy, gas chromatography and so on. Although these methods can carry out qualitative and quantitative analysis of PTA, they have the disadvantages of long analysis cycle, complex operation, time-consuming and labor-consuming, and cannot meet the efficient requirements of modern industry.

spectroscopic technique

In recent years, with the continuous development of spectral technology, the detection of PTA also ushered in a new breakthrough. Infrared spectroscopy, ultraviolet-visible spectroscopy and Raman spectroscopy are widely used in the quality control and analysis of PTA. These techniques have the advantages of simple operation, fast and accurate, and no sample pretreatment, which greatly improve the efficiency and accuracy of PTA detection.

chromatographic technique

Chromatographic techniques also play an important role in the detection of PTA, especially gas chromatography-mass spectrometry (GC-MS). GC-MS can carry out efficient separation and accurate identification of PTA samples, which has unique advantages for the detection of impurities and organic compounds in PTA, and provides reliable technical support for the quality control in the PTA production process.

2. Analysis Technology Innovative Applications

Data Analytics and Artificial Intelligence

With the development of big data and artificial intelligence technology, PTA's analysis technology has also shown a new trend. Using data analysis and machine learning algorithms, the key parameters in the PTA production process can be monitored and predicted in real time, the intelligent management and optimization control of the production process can be realized, and the production efficiency and product quality can be improved.

laser spectroscopy technique

Laser spectroscopy is one of the new development directions of spectroscopy in recent years, and it has been gradually applied in PTA detection. Laser Raman spectroscopy and laser induced fluorescence spectroscopy have the advantages of high sensitivity and non-contact detection, which can realize the rapid on-line detection of PTA samples, and provide a feasible scheme for real-time monitoring of the production process.

microwave heating technology

Microwave heating technology is also gradually applied in the production process of PTA, which mainly heats PTA raw materials through microwave radiation to achieve rapid heating and uniform energy distribution, thereby improving the reaction rate and product quality. Compared with the traditional heating method, microwave heating has the advantages of low energy consumption and high reaction efficiency, which provides new ideas and new technology support for energy saving and emission reduction in PTA production process.

Through the discussion of PTA detection methods and analysis techniques, we can not only understand the key technologies and methods in the PTA production process, but also see the continuous exploration and breakthrough of PTA industry in the field of technological innovation and application. I believe that with the continuous progress of science and technology and the continuous development of the industry, PTA detection and analysis technology will usher in a better future.
