Ethyl Lactate. Ethyl Lactate is an environmentally benign solvent. Lactate esters have found industrial applications in specialty coatings, inks, cleaners and standard cleaning products. The solvent market is estimated at between 3.5 to 4.5 million tonnes per year, at prices ranging from US$ 2.00 to US$ 3.75 per kilo.io-solvents are progressively replacing petrochemical solvents and ethyl lactate serves as a biodegradable and non-toxic solvent which is sought after especially in the field of microelectronics and complies with the quality demands of the semiconductor industry.
Titanium is very expensive because it is awkward to extract from its ores-for example, from rutile, TiO2. You can't use carbon reduction Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent.t has a relatively low density (about 60% that of iron). It is also the tenth most commonly occurri â¦ ng element in the Earth's crust. That all means that titanium should be a really important metal for all sorts of engineering applications. In fact, it is very expensive and only used for rather specialised purposes.
Titanium is a strong light metal that is corrosion resistant. It could be used for coins, and has been used to strike medals. However, there are problems in producing a sheet of the metal with a smooth enough surface for coinage purposes, and this increases the cost of producing coins in bulk using this metal.o get round the corrosion problem in modern coins various coatings have been used, from copper (modern UK 'coppers') and brass (German 5 and 10 pfennig) to nickel and chromium (Canadian post-war 5 cents), nickel alone (Finnish 1 & 5 markaa 1953-1962) or zinc (US cent of 1943).
