The term naphthenic acid, as commonly used in the petroleum industry, refers collectively to all of the carboxyUc acids present in cmde oil. Naphthenic acids [1338-24-5] are classified as monobasic carboxyUc acids of the general formula RCOOH, where R represents the naphthene moiety consisting of cyclopentane and cyclohexane derivatives. Naphthenic acids are composed predorninandy of aLkyl-substituted cycloaUphatic carboxyUc acids, with smaller amounts of acycHc aUphatic (paraffinic or fatty) acids. Aromatic, olefinic, hydroxy, and dibasic acids are considered to be minor components. Commercial naphthenic acids also contain varying amounts of unsaponifiable hydrocarbons, phenoHc compounds, sulfur compounds, and water. The complex mixture of acids is derived from straight-mn distillates of petroleum, mosdy from kerosene and diesel fractions (see Petroleum).

Comparative analysis directly compares two or more data sets in order to detect changes in the operating condition of mechanical or process systems. This type of analysis is limited to the direct comparison of the time-domain or frequency-domain signature generated by a machine. The method does not determine the actual dynamics of the system. Typically, the following data are used for this purpose (1) baseline data, (2) known machine condition, or (3) industrial reference data. 

The half-time (or half-life) of the reaction is independent of [A]o. The reciprocal of the rate constant, t = l/k, is referred to as the lifetime or the mean reaction time. In that time [A] falls to l/e of its initial value. The pharmaceutical industry refers to the shelf life or t90, the time at which [A]/[A]o reaches 0.90. Both t and t90 are also independent of [A]o. 

In chocolate milk, the muddy color of caramel is darkened by the addition of FD C Red 40 to give what the industry refers to as a Dutch chocolate shade. Blues and yellows are sometimes added to create a browner color.

As stated, much of this book is intended to be a guideline. It should not be construed that the material presented herein is the absolute requirement for any facility. Indeed, many organizations have their own policies, standards and practices for the protection of their facilities. Portions of this book are a synopsis of common practices employed in the industry and can be referred to as such where such information is unavailable or outdated. Numerous design guidelines and specifications of major, small and independent oil companies as wen as information from engineering firms and published industry references have been reviewed to assist in its preparation. Some of the latest published practices and research into fire and explosions have also been mentioned. 

The Aldrich Catalog. Aldrich Chemical Co., Inc., Milwaukee, Wisconsin.) Not your traditional hard-bound reference handbook, but a handy book, nonetheless. The company makes many compounds, some not yet listed in the other handbooks, and often gives structures and physical constants for them. As Aldrich is in the business of selling chemicals to industry, many industrial references are given. 

This chemical cross-reference has been compiled by extracting information from chemistry textbooks, industrial references, and chemical formularies back to the early 1800 s. Equivalents, definitions, and cross-reference entries were loaded into our computer, sorted into alphabetical order, and then merged into one master cross-reference which follows.

What is the current use of the research results Needless to say, the food industry has found use for a great deal of the information. The industry has used the knowledge to control processes and hence to develop better tasting food products. However, one of the most intriguing uses of the information has been in the development of flavorings. The first patent for the use of the Maillard Reaction to create processed flavor, as the Flavor Industry refers to it, was... 

Chromophore — The part (atom or group of atoms) of a molecular entity in which the electronic transition responsible for a given spectral band is approximately localized. The term arose in the dyestuff industry, referring originally to the groupings in the molecule that are responsible for the dye s color.

When ABS was first commercialized, there was much confusion in the plastics industry referring to it as a terpolymer. The system is not a terpolymer as butadiene is added to the reactor as a polymer along with styrene and acrylonitrile monomers. Polymerization causes SAN to be grafted to the rubber to produce a dispersible domain. It is indeed a requirement that the polybutadiene regions exist as a separate phase of a specified size. Since the domain size is critical to its impact properties, it is important that it is stable through compounding and processing steps [20].
