Huachang Chemical 1,3-butanediol technology fills the gap of domestic industrial production

Recently, Huachang Chemical's "1,3-butanediol pilot production technology" passed the Jiangsu Provincial Scientific and Technological Achievements Appraisal Conference
.
The appraisal committee unanimously agreed that the project developed acetaldehyde condensation reaction distillation, falling film evaporation acetaldehyde recovery, jet cycle hydrogenation and other technologies, and its completed pilot production line with an annual output of 200 tons realized the process flow penetration, the product purity ≥ 99.
5%, completed the development of industrial production process technology package, obtained 1 national invention patent, filled the gap of domestic industrial production technology, and the product performance indicators reached the international advanced level
.

As a safe and non-toxic synthetic chemical raw material, 1.
3-butanediol is not only used in daily chemical products, but also used in paint, anti-corrosion and other synthesis, and is also widely
used in the field of green environmental protection coatings.
In order to make this scientific research achievement land, Huachang Chemical has sharpened a sword for 6 years, and success has not come easily
.
From laboratory results to successful small tests in 2017, the success of pilot process packages in 2018, the investment of more than 20 million yuan in 2021 to build a pilot base, and the realization of pilot production and achievement appraisal
in 2022.

"Under the monopoly control of technology and product markets, the total annual output of global 1.
3-butanediol products does not exceed 30,000 tons, and its price is several times that of other butanediol products, which limits the application of
downstream industries.
" This project breaks the monopoly of foreign technology, forms its own proprietary technology, and builds the upstream and downstream industrial chain
of symbiosis and mutual benefit of Huachang's existing production.
Huachang adopts its own patented new technology and proprietary technology to complete the pilot production technology verification of 1.
3-butanediol, and the 1.
3-butanediol produced by the pilot plant is at the leading level in China in terms of product yield, product quality and material consumption; Compared with foreign countries, the quality of 1.
3-butanediol has reached the product quality standards
of foreign enterprises.
Li Changsheng, general manager of Huachang Chemical New Materials Company, said
.

It is reported that while grasping the core of the business, Huachang Chemical keenly grasps new trends, actively transforms organic chemicals, and has carried out long-term layout in the field of new materials, with continuous
results.
Relying on the strong industrial production foundation of the enterprise, they work closely with many domestic scientific research institutes, give full play to their respective advantages, establish a mixed-ownership technology research and development company, realize self-research and development, self-innovation, self-technical support, each with its own focus on exploring the synthesis and application of special chemicals, and accelerate the iterative upgrading
of new chemical materials.
In the next few years, it is expected to complete the technical qualification
of 2 to 3 new material products every year.
