Aromatic Chemicals

Phenolics and Specialty Products

RCI’s Aromatic Chemicals business line extracts pure products such as phenols, cresols and xylenols, carbazole, anthracene, as well as 3.5-xylenol and acetophenone — most of them derived from coal tar and other sources and produced at RÜTGERS’ facilities.

These substances, some of which can be custom mixed to meet stringent customer requirements, are essential in the manufacture of paints, drugs, agro-chemicals, fragrances, disinfectants, paper, dyestuffs, resins, etc.

Phenolics

Our Phenolic product range, manufactured by RÜTGERS, includes phenolic products and phenolic blends:

  • Phenol 98% or 99.5%: Derived from coal tar; mainly used as a solvent for wire enamels, in the manufacture of tanning agents and phenolic resins.
  • O-cresol 99% or 99.5%: Uses include phenolic resins for foundries, and as an intermediate for agro-chemicals.
  • M/p-cresol 98%: Pure M/p-cresol can be converted to resins, and is also used in the production of flame retardants.
  • Mixtures such as Novaphen SC 40, Novaphen SC 77 and Novaphen XR 40: The most important use for these mixtures of phenol/cresol/xylenol are as solvents for the coating of copper or aluminum wires. Their special qualities make them a crucial part of wire enamels. Special blends with extremely low ion content are used in the manufacture of photoresist resins in the microchip industry.

Acetophenone and 3.5-Xylenol

Alongside tar-based products, our Aromatic Chemicals line also manufactures two synthesis products, Acetophenone and 3.5-Xylenol at our RÜTGERS facilities.

  • Acetophenone is a versatile raw material used in a variety of chemical products. It is used in special resins, as a heat stabilizer in polyvinyl chloride, and as a intermediate for fragrance chemicals like (C-16 aldehyde and styrallylacetate).
  • 3.5-Xylenol is mainly used in the production of antiseptic agent PCMX which, for example, can be found in soaps and disinfectant solutions.

Carbazole and Anthracene

At our state-of-the-art RÜTGERS plant in Castrop-Rauxel, Germany, our Aromatic Chemicals business line uses a highly innovative, high temperature melting crystallization process for the solvent-free extraction of polycyclic aromatics such as anthracene and carbazole from coal tar. Coal tar contains approximately 1.3% anthracene, and 0.9% carbazole. After tar distillation, both substances are concentrated in the anthracene oil fraction.

  • Anthracene is required for the production of anthraquinone, which is used as a bleaching agent for pulp by the paper industry, and as a dyestuff precursor in the dye industry. Anthracene crystallizes in colorless to yellowish flakes that fluorescence violet and sublime easily. It was first isolated from coal tar by Auguste Laurent and Jean Dumas in 1832.
  • Carbazole is the key raw material for the high-performance pigment Violet 23 and for the denim dye Hydron Blue. Both are widely used in car varnishes, repair varnishes, printing inks, textiles and polymers. Carbazole, a yellowish solid that sublimes easily, was first discovered and identified in 1872 by Carl Graebe and Carl Glaser.

Carboindene

In addition to phenolic compounds, carbolic oil from coal tar contains c9-rich aromatic hydrocarbons, which also include indene, a colorless, aromatic liquid used in the production of hydrocarbon resins. These industrial resins, also known as coumarone-indene resins, are manufactured at our RÜTGERS plants. They can be processed further by our customers to make adhesives, sealants and coating materials.

SARATAN

SARATAN products are low molecular weight sodium poly-naphthalene sulfonates. SARATAN is a highly effective dispersant for a wide variety of pigments, including carbon black, mineral colorants, organic dyestuffs, fillers, extenders, clays, etc.

SARATAN stabilizes and reduces viscosity of thick pastes and produces a smooth, uniformly wet paste without separation of the solid particles. Used in the leather industry, SARATAN acts as a wetting and dispersing agent for staining dry leather, applying aqueous finishes and rewetting hides or crushed leather.

MANUFACTURE OF SYNTHETIC RUBBERS

SARATAN is used in combination with primary emulsifiers such as fatty acid soaps, disproportionate rosin acid soaps to prepare high solid content latexes, very stable towards pH variation. A very fine floc or ‘gums’ tends to form during the emulsion polymerization of styrene-butadiene rubber, nitrile rubber, and poly-chloroprene despite the presence of efficient primary emulsifiers.

The addition of a secondary dispersant/emulsifier such as SARATAN effectively minimizes the formation of gum.

A secondary dispersant is economically important because excessive gum formation in the reactors and in styrene stripping columns leads to frequent shutdowns for clean-up. SARATAN minimizes such formation of gum and allows rubber production facilities to operate for considerably longer periods of time before shutdown

Continuous investment in our state-of-the-art production facilities has helped RCI companies maintain a technical advantage – our customers can now join us in developing product specifications and innovations that fit their needs.

NOVARES®

Industrial resins are synthetic resins made for commercial use. Based on petrochemical or carbon feedstock, they can be manufactured in different chemical compositions and with different softening points depending on application. This means that each product can be given different hardening and adhesive properties as required for adhesives, paints or coatings.

NOVARES® resins is geared specifically to meet customer objectives. Customized softening points and individualized product forms, from pastilles to hot melts, pave the way for customers to manufacture innovative products that enhance their competitive edge and secure success.

The NOVARES® range of resins are of primary importance in the following industries:

  • Adhesives: As a result of technological advances in production processes, the use of adhesives has increased in recent decades. Instead of welding or riveting, parts — whether at home, in cars or in airplanes — are increasingly joined together by adhesives.
  • Coating: Resins like NOVARES® are also used in the production of coatings to protect all kinds of surfaces. Now, more than ever, the global trend is toward products which have less impact on the environment. RCI is focused on meeting this challenge.
  • Rubber: Human mobility and transportation have always been closely linked with the need to limit their impact on the environment. Among other things, the automotive industry has been responding with the design of more fuel-efficient engines. The rubber industry is also conscious of its responsibility towards environmental sustainability; manufacturing tires with our NOVARES® resins helps improve their rolling resistance and wear performance.

Modifiers

Non-reactive modifiers are used in coatings for industrial floors, as well as for moisture barriers, cable joints, pigment pastes and water-based adhesives. They are also used as solvents for dyestuffs, and as heat-transfer and electrical insulation oils. RÜTGERS' plants produce these modifiers under the brand names RUETASOLV® and KMC®.

  • RUETASOLV® allows customers to create products which are resistant to extremely adverse conditions. It is highly water resistant and can withstand exposure to extreme temperatures, chemical stresses, as well as extreme wet or dry conditions. Its low viscosity and high boiling point allows RUETASOLV® to be substituted for conventional solvents in epoxy and PUR systems.
  • Carbonless copy papers, used as text rolls or form-sheet sets, consist of several chemical layers that only develop their color formers after contact with the acidic content of CF/CFB sheets. Dyestuffs are dissolved in solvent and enclosed in microcapsules. KMC® is a chemically neutral hydrocarbon that prevents unwanted interaction with microcapsule materials or dyestuffs in these applications, even at elevated temperatures.
