What are the prospects for producing tert-butylamine via isobutylene amination?
Thread Content
Everyone is welcome to discuss the production of tert-butylamine via isobutylene amination; those who are interested can contact me on the platform to exchange ideas
Small quantities of chemical products can be profitable, but their market demand is relatively fixed; caution is needed when establishing new factories.
This route is definitely competitive and environmentally friendly
It is understood that the one-way conversion rate of this method is not high, and its selectivity is unsatisfactory. For the production of tert-butylamine, the isobutylene and hydrocyanic acid process is preferable, as it offers very high conversion rates and yields. Over 98%.
I have previously worked on the development of synthesizing tert-butylamine from MTBE and another cyanide-containing compound, with very good results – a yield of over 90%.
Are there any specific requirements for that equipment?
High pressure. Mainly, the demand for downstream products is not high! BASF’s production seems to be 16,000 tons.
The preferred production method for tert-butylamine is the synthesis of it from isobutylene or C4 fractions along with hydrocyanic acid or other cyanides; the conversion rate and selectivity are both above 90%, with by-products such as sulfuric acid being produced. The ammonia conversion and selectivity of isobutylene are not satisfactory; it can be used for research purposes, but industrial investment must be cautious and cost-effective.
The cost of isobutylene amination should be the lowest among several processes.
Not necessarily; due to low selectivity and low conversion rates, there are many practical problems such as difficulties in separating the downstream products, increased costs associated with raw material recycling, and so on. In the isobutylene and hydrocyanic acid process, hydrocyanic acid is a by-product of acrylonitrile production and can be considered valueless
I want to know why the conversion rate is so low
