Seeking cooperation or transfer for 1,6-hexanediol technology
Thread Content
I possess the technology for the esterification of adipic acid and hydrogenation to produce 1,6-hexanediol, along with the corresponding catalysts; I am seeking partnerships or technology transfers. The technology employs a catalytic distillation continuous esterification process, with the esterification catalyst having a service life of at least 5,000 hours ； Gas-phase fixed-bed hydrogenation under mild conditions ensures a conversion rate of dimethyl adipate of over 99.0%, with a selectivity for 1,6-hexanediol of over 97.0%. The tonnage consumption of adipic acid is no more than 1.30 tons.
LZ, whether to use phthalic anhydride or ordinary adipic anhydride for producing one ton of 1,6-hexanediol – what is the approximate cost? Assuming the price of adipic anhydride is 6,500 yuan per ton.
It is best to use high-quality adipic acid. Currently, the price of 1,6-hexanediol is above 20,000 yuan per ton, while the estimated cost, including factors such as energy consumption, material usage, and depreciation, is at most 15,000 yuan per ton
What scale have you reached currently, and what is the quality of 1,6-hexanediol?
The product purity can reach over 99.7%, meeting the requirements for subsequent polymerization.
What is the typical scale for 1,6-hexanediol production, what are the investment costs, and how much hydrogen is consumed in its production?
The investment for a plant with an annual capacity of 10,000 tons is around 600 billion, with a hydrogen consumption of 0.072 tons per ton of product produced
Currently, the price of 1,6-hexanediol in China is over 20,000 yuan per ton, but what is the market situation like?
This price is about 10% too high; the market size isn’t large； Related to wind power.
