The composition of montan wax depends on the material from which it is extracted, but all contain varying amounts of wax, resin, and asphalt. Black montan wax may be further processed to remove the resins and asphalt, and is known as refined montan wax. White montan wax has been reacted with alcohols to form esters. The wax component of montan is a mixture of long-chain (C24—C q) esters (62—68 wt %), long-chain acids (22—26 wt %), and long-chain alcohols, ketones, and hydrocarbons (7—15 wt %). Cmde montan wax from Germany typically has a melting point of 80°C, an acid number of 32, and a saponification number of 92. 

The largest traditional use for montan waxes was as a component in one-time hot-melt carbon-paper inks. With the decrease in the use of carbon-paper inks, uses for the refined grades have become predominant, mainly in the formulation of poHshes and as plastics lubricants. The alcohol ester derivatives may be used as components of articles intended for use with foods as regulated by the FDA in 21 CFR 178.3770. 

A variety of waxy hydrophobic hydrocarbon-based soHd phases are used including fatty acid amides and sulfonamides, hydrocarbon waxes such as montan wax [8002-53-7], and soHd fatty acids and esters. The amides are particularly important commercially. One example is the use of ethylenediamine distearamide [110-30-5] as a component of latex paint and paper pulp blackHquor defoamer (11). Hydrocarbon-based polymers are also used as the soHd components of antifoaming compositions (5) examples include polyethylene [9002-88-4], poly(vinyl chloride) [9002-86-2], and polymeric ion-exchange resins. 

Montan wax is obtained by solvent extraction of certain types of lignite or brown coal. It has a dark colour when not treated, but it is lighter when refined. Its chemical composition includes esters of C22 C32 acids (53%), free acids (17%), free alcohols (1 2%), ketones (3 6%) and terpenoids (20 23%) [85]. 

Montan wax is considered as a semimineral, intermediate between the vegetable and mineral waxes. It is extracted from brown coal or lignite. Chemically it consists of esters of wax acids,... 

Typical lubricants are fatty alcohols C]2-C22, fatty acids C14-Ci8, their esters with fatty alcohols, glycerol or pentaerythritol, amides (2) or diamides (3) and metallic soaps (see Heat stabilizers ), acids C28-C31 from montan wax and their esters, diesters of phthalic acid (4b), paraffin wax C2o-C70, PE waxes Ci25-C70o or their oxidized (polar) grades containing hydroxyl and carbonyl groups. 

Clariant is producing 11,000 metric tons per annum of bleached montan waxes in Gersthofen [104]. The starting material is deresinified crude montan wax, extracted from lignite. It consists of esters of long-chain alcohols and carboxylic acids. Montan wax acids and their derivatives are widely used, for example, as soaps, polishes, and lubricants. 

Crude montan wax (a mixture of esters of straight-chain saturated C26-C34 carboxylic acids) is a by-product of lignite and separated from lignite by an extraction process. Oxidative bleaching of black crude montan wax with hot chromosulphuric acid produces off-white, industrial montan wax acids. Esters of mono- and polyfunctional short-chain alcohols, esters of long-chain natural or synthetic fatty alcohols as well as complex esters are synthesized starting from montan wax acid [155].
