hydration of ethene vs fermentation

Membranes

When applied in a real fermentation broth the membrane showed high selectivity of 9 8 3 8 and 0 9 for butanol acetone and ethanol respectively A series of unsaturated silicone backbone containing polypropynes like polytrimethyl-silylpropyne (PTMSP) were tried for selective alcohol separation from its aqueous solution These membranes were found to yield very high permeation rate

Alcohols are produced industrially by hydration of alkenes in the presence of an acid catalyst Ethanol is produced industrially by fermentation of glucose The conditions for this process Ethanol produced industrially by fermentation is separated by fractional distillation and can then be used as a biofuel Oxidation of alcohols Alcohols are classified as primary secondary and tertiary

Solving Problems: A Chemistry Handbook

Chemistry is the study of matter and the changes that it undergoes Matter is anything that has mass and takes up space Mass is a measurement of the amount of matter in an object Everything how-ever is not made of matter For example heat light radio waves and magnetic fields are some things that are not made of matter You might wonder why scientists measure matter in terms of mass

Alcohol

In chemistry an alcohol is any organic compound in which the hydroxyl functional group (–O H) is bound to a saturated carbon atom The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol) the predominant alcohol in alcoholic beverages The suffix -ol appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the
