Seeking help with organic synthesis techniques
Thread Content
Our company has a large supply of high-purity isobutylene, and we are currently seeking technologies for the production of pivalic acid and methyl allyl alcohol. Those who are engaged in research in this area or who have expertise available for transfer can get in touch with me! Research institutes with expertise in this area can also be recommended!
Pentanoic acid – hydrocyanic acid is used for it. Methyl allyl alcohol is a by-product of the oxidation of isobutylene to produce MMA.
Do you know where I can find these two technologies?

Shandong XXXXXX Co., Ltd. has a methyl acroleate production facility with an annual capacity of 10,000 tons; the company has developed an environmentally friendly new process for producing methallyl alcohol through the oxidation of butane and hydrogenation. This process uses tert-butanol (or isobutylene) as a raw material, and it involves oxidation and hydrogenation to produce methallyl alcohol. The process consists of two main steps: the first step is the oxidation of tert-butanol to produce acrolein ； The second step is the hydrogenation of methacraldehyde to methallyl alcohol, with an atom utilization rate of 80%. During the development process, key technical issues such as poor hydrogenation selectivity and the prevention of methacraldehyde polymerization were resolved one after another.
We have a factory here; they wanted to produce methacrylic acid, but as a by-product, a large amount of methallyl alcohol was generated. It seems to be in Heze, Shandong; I heard about it as well.
{:3_50:} The pivalic acid we produce here does not require the use of cyanide; it is made from isobutylene and carbon monoxide, using concentrated sulfuric acid, under conditions of heat and pressure with catalysis, followed by hydrolysis and purification to obtain the final product. I’ve never seen that alcohol
{:3_47:} Concentrated sulfuric acid is 88%
Where does this technology come from? Can it be transferred?
I’m from Zibo, Shandong. This technology was provided by the boss’s former branch company; I really don’t know the exact source of this technology
There are many types of products that can be obtained through carbonylation, and if the catalyst has good selectivity, it can be quite competitive.
A plant has both hydrogenation units and oxidation units. How do you conduct your safety assessments/fire safety evaluations? Experts are everywhere
