“…Similarly, the absorption peaks corresponding to the main chain of Si-O-Si with wave numbers from 1000 cm −1 to 1100 cm −1 also decreased under the action of salt-fog, indicating that the degree of polymerization decreased. With the extension of test time, the decline trend is more obvious, indicating that the degradation is gradually getting worse [ 24 , 25 , 26 ].…”

Polymer insulators using silicone rubber materials as sheds and sheaths are widely used in power systems to replace traditional porcelain and glass insulators which are heavy, inconvenient to install, and prone to pollution flashover. However, in recent years, polymer insulators that have been operating in harsh outdoor environments for many years have experienced different degrees of aging. The aging degree and aging products of silicone rubber are the focus of research. Fourier transform infrared spectroscopy (FTIR) is a technical method to analyze the internal molecular bonds and functional groups of materials, and it is often used to study the aging degree and aging products of silicone rubber. In this paper, the aging characteristics of silicone rubber samples in a high altitude area, salt fog environment, and acid environment were studied by FTIR. The results showed that the silicone rubber in a harsh environment, such as strong radiation, salt fog, and acid fog was degraded to some extent, and its main chain was cut off, the degree of polymerization was reduced, and the content of hydrophobic functional groups was reduced. Infrared spectroscopy can be used to analyze the aging phenomenon of polymers.

A rapid benzylation of carboxylic acids was achieved under vacuum conditions and assisted by a rotary evaporator using p‐toluenesulfonic acid as a catalyst. Unlike the conventional method that utilizes the Dean‐Stark setup, which typically takes several hours or longer, benzylation was completed in 30 minutes without a solvent. Furthermore, this method avoids using BnBr or acyl halide as starting material and generates water as the only byproduct. This protocol is featured by its high yield, high atom economy, fast reaction, broad substrate scope, and easy operation. The rotary evaporator is commonly seen in chemistry labs, and there is great potential for exploring rotavap‐assisted organic synthesis.
