Hoverwork BHT130

The Hoverwork BHT130 is a medium-size hovercraft, designed by Hoverwork and fitted out in St Helens.

As a civil passenger hovercraft it seats up to 130 passengers, hence the numerics in its name, the first welded aluminium hull (fabricated by Aluminium Ship Builders, Fishbourne, Isle of Wight) arrived at Hoverwork's St Helens works in August 2005.

The first of its kind, named the Solent Express entered cross-Solent service on 14 June 2007; also, in the July of the same year, it was put on trial at a new passenger service between Kirkcaldy and Portobello across the Firth of Forth in Scotland.

Technical specifications

Butylated hydroxytoluene

Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. European and U.S. regulations allow small amounts to be used as a food additive. In addition to this use, BHT is widely used to prevent oxidation in fluids (e.g. fuel, oil) and other materials where free radicals must be controlled.

Occurrence

Phytoplankton, including the green algae Botryococcus braunii, as well as three different cyanobacteria (Cylindrospermopsis raciborskii, Microcystis aeruginosa and Oscillatoria sp.) are capable of producing BHT. Confirmation was made via gas chromatography–mass spectrometry analysis.

Production

Industrially, BHT is prepared by the reaction of p-cresol (4-methylphenol) with isobutylene (2-methylpropene) catalyzed by sulfuric acid:

Alternatively, BHT is prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation followed by hydrogenolysis.
