isopropyl alcohol or cumene peroxidation. (1) By Cumene Oxidation (Hock Process). Propene is added to benzene [71-43-2] to form cumene [98-82-8]‚ which is then oxidized by air to cumene hydroperoxide‚ and cleaved in the presence of an acid catalyst like zeolite. Phenol [108-95-2] and acetone [67-64-1] produced in the process are recovered by distillation. Ratio of phenol to acetone is 1:0.6. (2) By Dehydrogenation of 2-proponal The hydration of propene [115-07-1] gives 2-propanol [67-63-0]‚ which is

Objective To investigate the effect of carbon dioxide concentration on the rate of photosynthesis Introduction Photosynthesis is a process that is essential for every living organism. Organic substances‚ such as glucose‚ are made from carbon dioxide and water by light energy from the sun. The light energy is absorbed by chlorophyll and converted to chemical energy. During the process‚ oxygen is released as a by-product. The rate of photosynthesis is affected by a few of factors‚ including

Costs of Producing Biogas at Dairy Farms in The Netherlands 1 Introduction Anaerobic digestion of organic wastes and by‐products from agriculture and the food industry is a process known for many years and is widely used for waste stabilization‚ pollution control‚ improvement of manure quality and biogas production (Weiland‚ 2006). Biogas production from manure contributes to climate protection by reducing emissions of CO2 via substitution of fossil fuels and by reducing CH4 emissions from the

in proportion to its population. Domestic oil production declined at the same time‚ leading the country to lean heavily on foreign oil‚ and in 1973‚ the US was placed under an OPEC embargo for political reasons. Middle Eastern members of OPEC wished to protest American involvement in an ongoing conflict with Israel‚ and these nations struck the country where it hurt‚ depriving them of oil in 1973 and again in 1977. One of the most immediate effects of the embargo was skyrocketing energy prices

Investigating the effect of temperature on the action of a protease enzyme on exposed developed film Plan Aim: The aim of the experiment is to find out what effect temperature has on the action of a protease enzyme on exposed developed film. Enzymes are biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;
