Compared with other separation processes, melt crystallization offers advantages such as simplicity of operation, low energy consumption, cost efficiency, mild operating conditions, wide applicability, and environmental friendliness. These advantages have facilitated its further development. However, when applied to industrial production,…
A large amount of plastic waste enters the ocean every year, threatening wildlife and harming biodiversity. Additionally, microplastics and plastic microfibers have been found in the air and urban drinking water, causing health and ecological issues. Common but highly…
In today’s era of pursuing sustainable development, bio-based materials, with their eco-friendly and renewable properties, are gradually transforming the face of industries.Currently, the bio-based materials market is continuously expanding, with their applications extending beyond traditional fields such as packaging, agriculture,…
The recycling rate of PET waste plastics in China remains below 10% annually. The predominant recycling method is physical recycling, which, however, degrades the mechanical properties of PET, limiting the application scope of recycled PET products. While physical recycling of…
Under the “dual carbon” goals, a series of implementation guidelines have been introduced, unveiling vast potential in emerging blue oceans. Achieving carbon neutrality can be approached from three key directions: energy generation, energy consumption, and resource recycling. Examples include replacing…
Overview:The global annual production of polyolefins reaches as high as 150 million tons, but traditional polyolefins (such as PE and PP) have already seen capacity surplus. On the other hand, emerging fields such as new energy vehicles, optical materials, and…
Introduction Solid paraffin (also paraffin wax, hard wax, crystalline wax) is a petroleum-derived wax comprising predominantly straight-chain alkanes (C20–C40), produced as fully refined, semi-refined, and microcrystalline grades. It is thermoplastic, hydrophobic, and chemically inert, with adjustable melting points (typically 48–70°C),…
Introduction Nitrochlorobenzene (NCB) refers to mono-nitro, mono-chloro substituted benzenes with three main isomers: ortho-, meta-, and para-. They are foundational intermediates in dyes, agrochemicals, pharmaceuticals, and rubber chemicals, underpinning numerous downstream value chains. Common isomers and synonyms: o-nitrochlorobenzene (o-NCB), m-nitrochlorobenzene…
Introduction What is chlorotoluene? Chlorotoluene (monochlorotoluene or chloro-methylbenzene) is a family of isomeric chlorinated aromatics derived from toluene by chlorination on the ring. The three principal isomers are ortho- (o-), meta- (m-), and para- (p-) chlorotoluene. These colorless, hydrophobic liquids…
Introduction What is Monochloroacetic Acid (MCA)? Monochloroacetic acid (MCA), also known as chloroacetic acid or MCAA, is an organochlorine carboxylic acid with the formula C₂H₃ClO₂. It is a highly reactive building block used across diversified value chains, valued for its role…
