The McCabe–Thiele method is a technique that is commonly employed in the field of chemical engineering to model the separation of two substances by a distillation column. [1] [2] [3] It uses the fact that the composition at each theoretical tray is completely determined by the mole fraction of one of the two components.
Calcium acetate is a chemical compound which is a calcium salt of acetic acid. It has the formula Ca(C 2 H 3 O 2) 2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH 3 COO) 2 •H 2 O) is the common form.
Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).
Distillation apparatus. In chemistry, residue is whatever remains or acts as a contaminant after a given class of events. Residue may be the material remaining after a process of preparation, separation, or purification, such as distillation, evaporation, or filtration. It may also denote the undesired by-products of a chemical reaction.
The dry distillation of calcium acetate to give acetone was reported by Charles Friedel in 1858 [3] and until World War I ketonization was the premier commercial method for its production. [4] Ketonic decarboxylation of propanoic acid over a manganese(II) oxide catalyst in a tube furnace affords 3-pentanone. [5]
Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still.
Structural formula of the adipate dianion. The anionic (HO 2 C(CH 2) 4 CO 2 −) and dianionic (− O 2 C(CH 2) 4 CO 2 −) forms of adipic acid are referred to as adipates. An adipate compound is a carboxylate salt or ester of the acid. Some adipate salts are used as acidity regulators, including: Sodium adipate (E number E356) Potassium ...
With catalytic distillation, the company only needs to fund one column which eliminates both the cost for a second column and the cost to move chemicals from one column to another. This optimization cuts overhead costs to nearly half the original cost. [11] In addition to cutting costs, catalytic distillation is a milestone in efficiency and ...
