I’ll tell you the truth about PX
Thread Content
Let me tell you the truth – what exactly is this mysterious chemical called PX? Why, since the Xiamen PX incident in 2007, has people become terrified of PX? Almost every new PX facility triggers protests from local residents. A series of safety accidents in the chemical industry last year further put chemical production under public scrutiny. What exactly are the dangers of PX, can safe production be ensured, and why are chemical companies increasing PX production capacity? PX, a chemical term that once seemed very distant, suddenly appeared before us. What exactly is PX? CCTV reporters visited universities, laboratories, and enterprises both at home and abroad, striving to show the public the true face of PX. Videos related to CCTV’s live broadcast: 1. The truth about PX: It has low toxicity and minimal hazards, but a high flammability risk. 2. The truth about PX: It has a wide range of applications in daily life and is essential everywhere. 3. The truth about PX: Production capacity is insufficient, so the country relies on imports. 4. The truth about PX: Reporters visit countries that are major producers of PX. 5. The truth about PX: PX can exist in sunlight

It is also an important chemical material utilized in the production of polyesters, plastics, synthetic fibers, coatings, and more. Back in those days, China’s rayon fabric was made using PTA as the main raw material; it was an important synthetic fiber that helped solve the problem of clothing for the Chinese people at that time. A large amount of p-xylene is produced by reforming naphtha, and part of the products of this reforming process is p-xylene. However, if a greater quantity of p-xylene is needed, toluene must be subjected to disproportionation treatment, in which two molecules of toluene react to form one molecule of xylene and one molecule of benzene. Xylene is then isomerized to produce the desired p-xylene. This technology is already a mature and reliable one. The reason why the xylene project has become a focus of public attention is largely due to inadequate science popularization efforts in China; furthermore, large foreign producers of xylene and PTA are deliberately obstructing China’s efforts to build large-scale xylene and PTA projects. China imports a large amount of PTA every year; if China builds enough PTA production facilities, then those foreign PTA oligarchs will no longer be able to maintain high profits. There are too many people in China who do not know the truth, and coupled with the misleading tactics of those with ulterior motives like Chai Jing, who generalize things in a one-sided manner, this has led to a situation where fools follow those scammers and join in their nonsense.
