The 10,000 tons per year 1,4-butanediol (BED) production project at Ningxia Huaxufeng Zhihui is expected to begin individual equipment testing in December! In the Gaoshawo Industrial Park, Huaxufeng Zhihui (Ningxia) Technology Co., Ltd. is in full swing with the construction of a fine chemical plant with an annual production capacity of 10,000 tons of 1,4-butanediol and other similar products. Sparks fly at the construction site as tanks are assembled in an orderly manner; the main structure and underground pipeline systems have been fully completed, and equipment installation is over 60% done. Once operational, this project will focus on the manufacturing and sales of basic raw materials for use in the chemical and pharmaceutical industries, thereby injecting new momentum into the development of the fine chemical industry in our county. https://p3-sign.toutiaoimg.com/tos-cn-i-axegupay5k/36fe2d3538f249c1bc18cedea4d0724d~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1765436849&x-signature=k68%2F0q2WkuJ2zAiRca0EtsM6Vyc%3D “The project covers an area of 235 mu, with a total investment of 120 million yuan for the first phase. To date, the overall progress of the project is in line with expectations; the main structure and underground pipeline systems have been completed, and 60% of the equipment installation work has been done. It is expected that the equipment will be ready for individual testing in December. ”said the deputy administrative director of Huaxufeng Zhihui (Ningxia) Technology Co., Ltd. The project is planned to cover an area of 236 mu, with a total investment of 300 million yuan, and will be constructed in two phases. Phase 1: Construction of a 10,000-ton/year production line for 1,4-butanediol and a 10,000-ton/year production line for n-propyldioctylcyclohexane (purity ≥98%) ； Phase II involves the construction of a production line for 1,4-butyne diol with an annual capacity of 20,000 tons, a production line for ethyl 6,8-dichlorooctanoate with an annual capacity of 1,000 tons, and a production line for propargyl alcohol with an annual capacity of 3,500 tons. 1,4-Butenediol (BED) is widely used in fields such as pesticides, pharmaceutical intermediates, the chemical industry, batteries, papermaking, and leather manufacturing; it can be used to synthesize n-propyldioseptane, a key intermediate for vitamin B6. The production process of BED involves the semi-hydrogenation of 1,4-butyne diol (BYD), followed by further distillation. Its raw materials are intermediate products produced from BDO; both the by-product BDO generated from BED and n-butanol can be reused in BDO production. The main downstream uses of BED are the production of vitamin B6 and the broad-spectrum insecticide endosulfan; the consumption of BED for these purposes is 20,700 tons per year and 3,160 tons per year respectively ； Furthermore, BED can be used to produce 1,4-dicyano-2-butene, which can be further hydrogenated to yield hexamethylenediamine. Hexamethylenediamine and adipic acid can, under certain reaction conditions, be used to produce nylon 66 salts; this approach allows for breaking the technical monopoly associated with hexanitrile in the production of nylon 66 (hexanitrile can be hydrogenated to produce hexamethylenediamine). Huaxufeng Zhihui (Ningxia) Technology Co., Ltd. was established on September 11, 2023, and is located in the Baota Industrial Park, Gao Shawo Town, Yanchi County, Ningxia Autonomous Region. Its registered capital is 50 million yuan, and the legal representative of the company is Wang Zhenghong. The company’s business scope includes the production of basic chemical raw materials (excluding the production of chemicals that require special permits, such as hazardous chemicals). Currently, it has projects under construction for the production of 10,000 tons per year of 1,4-butanediol and 10,000 tons per year of n-propyldioxane.
