Factors affecting production

The most impoi tant factor affecting product quahty is the material balance. In separating a feed stream F into distillate D and bottom B products, an overall mole-flow balance must be maintained ... 

Once the material and heat balances are complete, a report must be written. It will first present the data. It will then discuss factors affecting product quality and any abnormal results. It will then discuss the key findings and recommendations to improve unit operation. 

Additional insight into the factors affecting product structure was obtained by study of the condensation of 2-butanone with benzaldehyde.2... 

Risk based regulatory scrutiny that relates to the level of scientific understanding of how formulation and manufacturing process factors affect product quality and performance and the capability of process control strategies to prevent or mitigate risk of producing a poor quality product. 

Product and process specifications based on an understanding of how formulation and process factors affect product performance... 

If such a model-based process design space includes a sufficient portion of the factors affecting product quality variance, the process control space can be projected to define the bounds of normal operation. Based on this definition, the control...

Typical yields have been provided for many synthetic reactions, although I hope students will not misuse these numbers. Too often students consider the yield of a reaction to be a fixed characteristic just as the melting point of a compound is fixed. In practice, many factors affect product yields, and literature values for apparently similar reactions often differ by a factor of 2 or more. The yields given in this book are typical yields that a good student with excellent technique might obtain. 

Free Radical Processes. Homolytic alkylation and arylation of pyridines has been studied extensively and reviewed (U ). The products are almost invariably mixtures of several Isomers depending on the nature of the pyridine substrate, the free radical (audits method of generation) and the type of medium in which the reaction is carried out. Tho gh early reports suggested 2-, and -substitution exclusively, more sensitive analytical techniques have shown the earlier claims to be erroneous 6ind studies into the various factors affecting product formation have been reported (1 6-62).

The temperature of operation greatly affects the product distribution obtained with iron, as shown in Fig. 11-6. The gasoline yield increases as the temperature increases, while the yield of heavier products decreases. A similar shift of products to lighter material occurs when the alkali content of the catalyst is decreased. Thus, the two main factors affecting product distribution are temperature and alkali.
