Benzyl chloride is one of the most important chlorinated intermediates used in pharmaceuticals, fragrances, dyes, and agrochemicals. Its purity and stability directly determine the yield and color tone of downstream products such as benzyl alcohol, benzyl acetate, and phenylacetic acid. Even trace amounts of moisture or unreacted toluene can cause polymerization or discoloration during synthesis. Our plant adopts a closed-loop chlorination process combined with automatic temperature and chlorine flow control, ensuring full reaction efficiency and consistent product quality. The reaction is precisely maintained between –5°C and 40°C, with chlorine utilization exceeding 98% and final purity reaching 99.8–99.9%. The entire system is equipped with inert gas protection and vacuum distillation units to prevent oxidation and ensure low color index (

Changzhou Xindong convened a special symposium recently to discuss matters related to the entry of its electronic-grade hydrogen peroxide into the semiconductor industry chain. The meeting invited professionals from the domestic semiconductor industry to participate. Combining the current stage of process technology with the quality improvement and transformation of New East's electronic-grade hydrogen peroxide, the meeting conducted technical exchanges on how to optimize processes and minimize costs. General Manager Wang Chengjun pointed out that New East Company's G5 electronic-grade hydrogen peroxide is an important engine for enhancing productivity and an economic growth point for Changzhou Xindong. He emphasized that all of us, as technology and management practitioners, need to raise awareness, strengthen cooperation, and take the establishment of the "G5 Electronic-grade Hydrogen Peroxide" special team as an opportunity to enhance communication with technical partners. The goal is to optimize processes and minimize costs, propose practical solutions, and promote New East Company's entry into the semiconductor terminal market as soon as possible, injecting new momentum into Changzhou Xindongs technological innovation and high-quality development.

In the ongoing process of promoting the standardization of team safety, the precision factory is starting from the details, filling in the gaps, not overlooking any loopholes, and not missing any blind spots. It is strengthening the sense of responsibility and strictly adhering to safety standards, making "I want safety" a conscious action. Finger-mouth dual confirmation, standard operation ensures safety. When adjusting the valve, the on-site operator verbally confirms while the DCS control personnel verify the valve number before operation, further ingraining standardized operations, eliminating risks at the micro-level, and addressing hidden dangers invisibly, thereby avoiding accidents due to insufficient two-way communication. Through standard operation cards and the oral and experiential teaching of senior employees, new employees are helped to develop good operating habits, reducing the risk of operating errors such as bad practices. Visible management clarifies responsibilities, and information means promote improvement. The key to visual management is to root the elements of visual management on the ground, make reasonable plans for the area, make everything clear at a glance, and facilitate the rapid adoption of corresponding measures at critical moments. Developing good safety habits and a sense of ownership, ingraining standardized operations in the minds of every employee, thus solidifying the foundation of safety production management, effectively preventing, resolving, and controlling various risks. Strengthening skills through post training, emergency response turns risks into manageable situations. Through regular post training and on-site firefighting parameterized assessments, employees truly integrate theory with practice. The precision factory treats every post training as the last opportunity, practicing as if it were wartime, treating wartime as if it were peacetime, making safety production a conscious action for every employee.

On April 23, Ma Xue and Zang Anqi, hazardous chemicals inspectors from Changzhou Customs, visited China Salt Changzhou for on-site inspection and sampling of exported hydrochloric acid. The two inspectors carefully examined the export packaging labels, marks, and overall packaging, all of which fully met the customs requirements. Under the new customs inspection policy, they also sampled the batch of hydrochloric acid and observed the daily sampling process for hydrochloric acid. Subsequently, the two inspectors held a discussion with Guo Aibing, Manager of International Trade at China Salt Changzhou. Ma Xue first thanked Changhua for its support to the customs inspection department's work and then introduced the latest sampling system for hazardous goods under customs inspection to Manager Guo. We also expressed our commitment to studying the new customs regulations for sampling and strictly adhering to customs requirements to complete the sampling work for 2024. This exchange has enhanced cooperation and understanding between the two sides, laying a good foundation for closer cooperation in the future.
