Epoxidation

Epoxidation

Epoxidation is a useful chemical reaction – the products of which have many uses in different markets, such as epoxidised soy oils as acid scavengers, making linear epoxides for derivatisation for composite materials, making 1,2-diols for personal care or complicated ring epoxides for F&F as well as intermediates for Pharma and Agchem. The technology is versatile and is seen in many synthetic applications in a diversity of markets.

Here, using catalysts, hydrogen peroxide is used to form the epoxide, which can then be used to make diols, react with nucleophiles etc.

The fractionation capabilities mean that we can separate and recover, unreacted olefins if necessary, and we can distil and dry the resulting epoxide and remove it from any catalyst used.

The epoxidation can be done with various catalysts including polyvalent complexes, Phase transfer based catalysis, and at varying temperatures depending upon the nature of the reaction, steric hindrance etc.

Chemoxy produces specialty epoxides and uses several technologies, handling raw materials such as aliphatic and complex cyclic alkenes and uses a range of catalysts.

Chemoxy’s skill set, allows the products to be produced in high purity with low water content, often required as part of the specification, whether used in pharma, agrochemicals, F&F, electronics or other performance applications.

Products are isolated by intensive distillation fractionation, and thus there are benefits in the ability for us to achieve high purity and low water content, and to recycle acids and alcohols.

We can also produce materials which are not distilled and have high melting points by dropping the melt to drums, or to a flaker.

Our preference is for liquids, or products that melt below 50ºC.

One such product we make is Chemoxycare®8.
