Naming conventions: acids aromatic compounds

Elforts have been made to characterize the nature and content of individual components that are present in the low-molecular-mass fraction of the total mill effluents, which include the spent chlorination and alkali extraction stage liquors [2,4]. Approximately 456 types of compounds have been detected in the conventional bleach effluents, of which 330 are chlorinated organic compounds [22]. The compounds may be lumped into three main groups, namely, acidic, phenolic, and neutral (Table 2). Acidic compounds are further divided into the five categories of acids fatty, resin, hydroxy, dibasic, and aromatic acids. The most important fatty acids are formic and acetic acids. The dominant resin acids are abietic and dehydroabietic acids. Among the hydroxy acids identified, glyceric acid predominates. Dibasic acids such as oxalic, malonic, succinic, and mafic acids are derived from the lignin and carbohydrate fraction... 

Liquid crystals formed through pressure change have been named barotropic. Barotropic behavior is observed not only for flexible polymers, it is also rather popular for conventional thermotropic liquid crystalline compounds and polymers. It has been reported by several research groups (e.g., Herrmann et al, 1983 Chandrasekhar and Shashidhar, 1979 Stevens et al., 1984). As an example, Hsiao et al. (1988) claimed that for the aromatic copolymer of 4-hydroxybenzoic acid (20 mol %), hydroquinone (40 mol %) and 1,3-phthalic acid (40mol %), not only would the temperature range of the liquid crystalline phase formed at normal pressure increase with increasing pressure, it would also form a new liquid crystal phase at high pressure.
