IoLacTec:
INNOVATIVE METHOD FOR ACIDIC IONIC LIQUIDS MEDIATED LACTAMS PRODUCTION

LEADER PROGRAMME

The aim of the project is to design and optimize a new technology for the production of lactams, including ε-caprolactam through Beckmann rearrangement of oximes in the presence of ionic liquid as catalyst and solvent.

Did you Know?

  • Lactams, including ε-caprolactam are fine chemical intermediates in the polyamides production (nylon 6, 11, 12) which are key component in the automotive, electrical, textile and medical industry.
  • The classical process is catalyzed with oleum and requires neutralization of the reaction mixture with ammonia what generates a by-product: ammonium sulphate.
  • The biggest producer of ε-caprolctam in Poland is Grupa Azoty, producing 170 000 tons of ε-caprolactam per year.

Our goal

The technology will be based on the one pot, rearrangement of oximes to lactams in the presence of ionic liquid. This method does not require use of ammonia to isolate the product thus does not generate the ammonium sulphate as a waste. The product will be isolated by extraction with an organic solvent. Within the project the large number of oximes will be investigated what will widen the group of products produced by this method. Based on this, the results of the project will cover the process innovation novelty

The technology aims to possess the following features:

  • Lack of the neutralization step = lack of the ammonium sulphate as a by-product
  • High yield and selectivity of the product
  • Short reaction time
  • Easy isolation of the product
  • Possible recovery of the catalyst

Four steps will be optimized:

01

Preparation of the catalyst

02

Synthesis of lactams

03

Isolation of products and catalyst

04

Purification of the products

Next, The development of a complete technological route for lactams synthesis on example of ε-caprolactam will be performed.
