Chlorine Chemistry and Titanium Dioxide, Adding Brightness to Life

Titanium is a highly versatile metal used in applications from aircraft engines to artificial hips. But it is in the form of titanium dioxide (TiO2) that this metal finds its biggest market. TiO2 has a pure white colouring, is very reflective and is resistant to UV radiation. All these characteristics make it an ideal pigment for paints, ceramics, plastics and papers.

Staying Sugar-Free with Acesulfame Potassium

According to the World Health Organisation, worldwide obesity has nearly tripled since 1975. The problem is that we are consuming more calories than we are using, which leads to a build-up of fat in the body. Sugar is a major source of calorie intake in our diet. In fact, satisfying our craving for sweet tastes but avoiding the calories that come with sugar, is how sugar substitutes came into being in the first place.

Potassium Carbonate, Contributing to Better Chocolate

The origins of chocolate stretch back to the 18th century when a Swedish botanist, Carolus Linnaeus, gave the cocoa tree its Greek name Theobroma Cacao, which means “food of the Gods.” However, it was during the 19th century that many of the innovations and improvements in chocolate production were developed. The first conche (a machine, used during the manufacture of chocolate, which mixes and smooths the chocolate mass) was developed in 1879 by Rudolph Lindt. Daniel Peter found a way to blend milk into chocolate in 1876, and Casparus Van Houten created the cocoa press in 1828. But one of the most significant developments was the introduction of alkaline salts by Coenraad van Houten in 1828.

Chlorine - a Versatile Chemical Building Block

Chlorine is one of the most common chemical elements occurring in nature - even more common than carbon. It makes up 2.9% of the world’s oceans in the form of sodium chloride (salt). Chlorine’s high reactivity means that it almost never occurs on its own, but is instead always bound to another substance in compound form.

How Potassium-Based De-Icers Ensure Safe Air Travel

Ice and aircraft are a dangerous combination. On 17 November 2018, a passenger aircraft partially slid off the taxiway at Denver International airport. Fortunately, the plane was not moving too fast when it hit the ice, and none of the 85 passengers or 6 crew were injured. However, the incident highlights just how dangerous it can be for an aircraft to encounter ice on the runway.
