Product family units

Unit sales prices of from 800 to 900 fine chemicals are fisted weekly in the Chemical Marketing Reporter. This number reflects those fine chemicals produced and sold in industrial quantities. Some market studies on fine chemicals, fisting important product families, such as side chains for P-lactam antibiotics (qv). A/- and A-heterocycfic compounds, fluoroaromatics, etc, do exist (14,15). 

Based on Wallace (2004), Sales and Operations Planning (S OP) is a business process that helps companies keep demand and supply in balance. It does that by focusing on aggregate volumes (e.g., product families or product groups), so that, mix issues (individual products and customer orders) can be handled more readily. It occurs on a monthly cycle and displays information in both units and dollars, thus it integrates operational and financial planning.

Of the worldwide ethyleneamines capacity, over 50% is EDC-based the balance is rnonoethanolarnine-derived. A complete breakdown of the ethyleneamines capacity by product is not feasible siace most manufacturers can vary production mix to meet market demand. A rough estimate is that EDA represents about 40% of the total production of the family of ethyleneamines. In Europe, the product mix is skewed somewhat more toward EDA. Prices of the principal commercial polyamines ia 1992, ia the United States, are given ia Table 4. 

Displacement-purge forms the basis for most simulated continuous countercurrent systems (see hereafter) such as the UOP Sorbex processes. UOP has licensed close to one hundred Sorbex units for its family of processes Parex to separate p-xylene from C3 aromatics, Molex tor /i-paraffin from branched and cyclic hydrocarbons, Olex for olefins from paraffin, Sarex for fruc tose from dextrose plus polysaccharides, Cymex forp- or m-cymene from cymene isomers, and Cresex for p- or m-cresol from cresol isomers. Toray Industries Aromax process is another for the production of p-xylene [Otani, Chem. Eng., 80(9), 106-107, (1973)]. Illinois Water Treatment [Making Wave.s in Liquid Processing, Illinois Water Treatment Company, IWT Adsep System, Rockford, IL, 6(1), (1984)] and Mitsubishi [Ishikawa, Tanabe, and Usui, U.S. Patent 4,182,633 (1980)] have also commercialized displacement-purge processes for the separation of fructose from dextrose.
