peer agreement (net): +2| soda cook => NaOH cocção com soda caustica Explanation: soda cook => NaOH => cocção com soda caustica Sodium hydroxide Chemical Compound Sodium hydroxide, also known as caustic soda, or lye, is an inorganic compound with the chemical formula NaOH. It is a white solid, and is a highly caustic metallic base and alkali salt. Wikipedia Formula: NaOH Molar mass: 39.997 g/mol Density: 2.13 g/cm³ Melting point: 604.4°F (318°C) IUPAC ID: Sodium hydroxide Boiling point: 2,530°F (1,388°C) The underlying chemical principles of this process are practically the same as those of the soda process except for the complications introduced by the presence of sulfur compounds. Sodium sulfide probably acts very much like caustic soda in the digester, but it may well be that it reacts first with water to form sodium sulfhydrate, which then reacts with the wood very much as caustic soda. This reaction between sodium sulfide and water to form sulfhydrate and caustic soda is reversible and takes place only as the caustic soda is taken up by the wood. The chief function of the sulfide in the cooking liquor is, therefore, quite likely that of forming a reserve supply of alkali which can be used as needed, but which is not all immediately available at the beginning of the cook. This automatically controlled cooking condition differs from that of a soda cook in which all the available alkali is present at the start, thus causing the action to vary from drastic at first to rather mild at the end. It is probable that this restraining influence of the sulfide is responsible for the higher yields and strength of sulfate pulps. http://www.oldandsold.com/articles10/paper-making-7.shtml Pg. 17.
