Automotive Grade Urea used to manufacture AdBlue is produced from natural gas. The current conflict with Ukraine/Russia and subsequent sanctions imposed, have caused the price of natural gas to soar and has again reached a record high.European Urea manufacturers have already started to take the decision to implement either plant shutdowns or reduce production because the cost of production is too high. This in turn has led to the cost of urea and therefore AdBlue once again rising in price.

A is for …. AdBlue®

Over the next few months were going to be publishing a complete guide to this mysterious liquid and how it will affect you, your car and your wallet/ can there’s no better place to start than with the letter……A

A is for (obviously) AdBlue®

Over the coming weeks we’re going to be giving you a complete A-Z rundown of this mysterious liquid they call AdBlue® and there’s no better place to start than with the letter …..A

AdBlue® is not Blue.

It is a colourless liquid.

AdBlue® is not made from pigs wee.

However, AdBlue® IS made up of a synthetic reproduction of a very common liquid ‘Urea’, the main nitrogen-containing substance in the urine of mammals.

Urea was the first ever organic compound to be synthetically formulated.

Way back in 1773, Hilaire Marin Rouelle a French chemist isolated the crystalline substance and six years later (why it took so long I don’t know) Antoine François de Fourcroy and Louis Nicolas Vauquelin came up with the name ‘Urea’.

It was some time later in 1828, when German chemist Friedrich Wöhler heated a solution consisting of a mixture of silver cyanate (AgOCN) and ammonium chloride (NH4Cl).

This formed ammonium cyanate, a substance that when heated more became a clear, colourless crystalline urea which has the same characteristics as urinary urea.

Fast-forward to today

The commercial production of synthetic urea now involves the reaction of ammonia and carbon dioxide under high pressure (approximately 150 atm) and at high temperature (approximately180°C).

The product, ammonium carbamate (CO2NH4NH2), is then dehydrated to produce urea (Carey 1992; Myers 2007). A summary reaction is shown below:

2NH3 + CO2 —–> CO2NH4NH2 —–> CO(NH2)2 + H2O
