Regulation mutual conformation

The selective catalysis by the immobilized 3-CyD catalysts proceed in a similar manner to that by free 3 CyD catalyst (13). The 3-CyD residue forms a ternary molecular complex with phenol and trichloro-methyl cation, produced in situ from carbon tetrachloride with the catalysis by copper powder. As a result, the mutual conformation between phenol and trichloromethyl cation is regulated through the non-covalent interactions. The para-carbon atom of phenol is predominantly attacked by the cation, since the carbon atom is located in close proximity to the cation. 4-Hydroxybenzoic acids are selectively formed by the hydrolyses of the C-Cl bonds in the resulting intermediates. 

The discussion of the complete flow of information goes far beyond the scope of this chapter. Therefore, we will focus on discussing selected illustrative examples Customer and regulation bodies will provide requirements for the product and the production system to the plant owner. The customers will define the product characteristics (e.g., product type and quality, amount) resulting in the definition of the production process to be executed on the production system. The regulation bodies will define safety-related product requirements (like CE conformity) and production system-related safety and workforce requirements (like protection guidelines from the employers mutual insurance associations). All these kinds of information are related to function-related information or further technical information.
