It encompasses all critical aspects necessary for Butynediol production, including the cost of Butynediol production, Butynediol plant cost, Butynediol production costs, and the overall Butynediol production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a Butynediol production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.

Butynediol (1,4-Butynediol) is an organic compound, an alkyne and a diol, utilised as a chemical intermediate having both hydroxyl and alkyne functionalities. It is used in pesticide production as a precursor to synthesise active ingredients that enhance crop protection efficacy through improved solubility and stability.

Its derivatives function as corrosion inhibitors in metalworking fluids and coolants to form protective films on metal surfaces to prevent degradation during industrial processes. In polymer production, it acts as a plasticiser in synthetic resins and polyurethanes, boosting flexibility, resilience, and processability for applications in coatings, adhesives, and sealants. Additionally, it finds a role in electroplating baths to brighten nickel coatings and promote uniform deposition. Moreover, its emerging applications include fuel additives for optimised combustion and biomedical systems for controlled drug delivery.

The market growth for butynediol is propelled by surging demand in pesticide synthesis, where it acts as a precursor for active ingredients, along with its role in corrosion inhibitors for industrial fluids. The expansion in polymer sectors, mainly polyurethanes and resins requiring enhanced flexibility, drives demand as manufacturers optimise formulations for coatings and adhesives. Additionally, rising needs in electroplating for bright nickel finishes and emerging bio-based applications amid sustainability pushes, along with global trade volumes supporting supply chain dynamics, fuel market expansion. Industrial butynediol procurement is influenced by fluctuating raw material costs, mainly crude oil-derived feedstocks like acetylene and formaldehyde, which drive production expenses and price volatility.

Raw Material for Butynediol Production

According to the Butynediol production plant project report, the various raw materials for Butynediol production include formaldehyde and acetylene.

Production Process of Butynediol

The extensive Butynediol production cost report consists of the following major industrial production process:

1. Production via Reppe ethynylation process: The production process of butynediol occurs through the Reppe ethynylation process. The process involves the reaction of formaldehyde with acetylene over a supported copper-bismuth (Cu-Bi) catalyst. The CuO-Bi2O3 catalyst, coated on inert supports like silica gel or pumice with 20-30 wt% Cu and 2-9 wt% Bi, undergoes in-situ activation to copper acetylide in aqueous formaldehyde under mild acetylene pressure (60-100 degree Celsius, 0.1-0.15 MPa). The ethynylation process occurs in slurry reactors with metal membrane filtration for continuous clear product withdrawal or fixed-bed/trickle-bed setups, producing butynediol.

Properties of Butynediol

1,4-Butynediol (HOCH2C≡CCH2OH) is a hygroscopic, colourless to white solid with a molecular weight of 86.09 g/mol. It has a melting point of 58 degree Celsius, boiling point of 238 degree Celsius, and density of 1.07 g/cm³. It has high solubility in water, ethanol, and acetone but low solubility in non-polar solvents. Its diol-alkyne structure enables hydrogenation to 1,4-butanediol, oxidation, and substitution reactions important for synthesising pesticides, corrosion inhibitors, polymers, and electroplating additives. It shows sensitivity to strong acids, mercury salts, and high temperatures, potentially leading to decomposition.
