TL;DR: In this paper, a series of eight Tertiary coal and carbonaceous shale samples with vitrinite reflectance values between 0.50 and 0.58% were extracted, fractionated and the saturated and aromatic hydrocarbons analysed for characteristic components by GC and GC-MS.

TL;DR: In this paper, a polyacrylic acid resins are prepared by polymerizing H 2C=CHCO2H, H 2 C=CRCO2X, or HRC=CH CO2X.
Abstract: Novel polyacrylic acid resins are prepared by polymerizing H2C=CHCO2H, H2C=CRCO2X, or HRC=CHCO2X, wherein R is an aliphatic or aromatic hydrocarbon, halogenated hydrocarbon, or sulfonated hydrocarbon of from C1 to C20, phenol, naphthol, sulfonated phenol, sulfonated naphthol, or a halogen, and X is hydrogen, alkyl, or a hydroxylated, ethoxylated, sulfonated, or halogenated aliphatic or aromatic hydrocarbon of from C1 to C20, sodium, potassium, ammonium, or quaternary amine, in the presence of aromatic sulfonic acid or its salt to form a polymer in which the sulfonated aromatic compound is covalently bound to the polymer. In an alternative embodiment, a textile processing or cleansing compound is included in the polymerization reaction along with the acrylic acid and aromatic sulfonic acid or its salt. The resulting polymers have superior properties for use in textile processing and cleaning, and can be used as detergents, acid dye levelers, surfactans, emulsifiers, yarn lubricants, copolymerizing agents, polymer after treat agents, defoamers, chelating agents, flocculants, anti-static agents, flame retardants, metal cleaners, metal coatings, and as multipurpose acids.

TL;DR: In this article, the phase equilibrium properties of N-methyl-2-pyrrolidone and N-hexadecane with an aromatic hydrocarbon were investigated at 298.2 K and 1 atm pressure.
Abstract: Tie lines and liquid−liquid equilibrium data are presented for mixtures of an n-alkane + toluene + N-methyl-2-pyrrolidone and mixtures of n-hexadecane + an aromatic hydrocarbon + N-methyl-2-pyrrolidone at 298.2 K and 1 atm pressure. n-Alkane refers to n-hexane or n-nonane or n-tetradecane or n-hexadecane, and an aromatic hydrocarbon refers toluene or o-xylene or m-xylene or p-xylene or mesitylene or ethylbenzene. N-methyl-2-pyrrolidone is an important solvent used in the extraction of aromatic compounds from alkane−aromatic mixtures. The data presented here complements data in the literature and gives a broader description of the phase equilibrium properties of the mixtures generated by an n-alkane + an aromatic hydrocarbon and N-methyl-2-pyrrolidone.
