The Chemistry of Proteins

The purpose of this booklet in The Unilever Advanced Series was to explain proteins to post-16 students as simply as possible in chemical terms, while putting the subject into the context of the biochemical significance of the molecules. The booklet was first published...

The Hydrogenation of Soft Oils

Details of this challenging experiment were published in this leaflet from the Unilever Laboratory Experiment in 1965. Requirements included a pyrophoric nickel catalyst supplied by Unilever, hydrogen from a cylinder and a vegetable oil treated with activated charcoal to remove impurities. The necessary apparatus...

The Preparation of Soap

This Unilever Laboratory Experiment describes the preparation of soap from a mixture of cooking oil and dripping. The leaflet was first published in 1964 and so lacks modern safety guidance. The procedure is authentic; it is designed to produce a convincing sample of soap. This means that it could be the basis of...

The Preparation of Sodium Alkyl Benzene Sulphonate

The method of preparation of a sulphonate paste described in this Unilever Laboratory Experiment is basically the same as that used by Unilever in the large-scale production of soapless detergents at the time of publication in 1964. The required reactants included an alkylbenzene hydrocarbon supplied by the...

The Rusting of Steel
