GENERAL DESCRIPTION OF ALKYNE
Alkynes are aliphatic hydrocarbons that have one or more carbon-carbon triple bonds. The general structure of alkyne hydrocarbons with a triple bond is CnH2n-2. They are insoluble in water but easily soluble in common organic solvents of low polarity. The characteristics of alkynes in chemical synthesis are due to the acidity of hydrogen atoms bonded to triple bonded carbons as well as to the triple bonds themselves. Addition reactions are typical of alkyne reactions; halogenation, hydrogenation, hydrohalogenation, hydration, oxidative cleavage, nitrile formation and acidity of terminal alkynes. Polymerization and substitution reactions are also useful in chemical synthesis.
Addition reactions
Catalytic hydrogenation by Pt and Pd hydrogenation catalysts to produce alkanes without isolation of alkene intermediates.
Catalytic hydrogenation by Lindlar catalyst to produce cis- or trans-alkenes without further reduction to alkanes
Addition by electrophilic reagents
Addition of halides (chlorine, bromine, iodine) to produce dihalogenated alkanes substituted at the solid binding site
Addition of hydrogen halides (HCl, HBr, HI) to produce monohalogen substituted alkenes or dihalogen substituted alkanes
Hydration of alkynes to give ketone products by the enol tautomeric intermediate step, while hydration of solid bonds gives alcoholic products (exceptionally acetylene gives acetaldehyde).
Hydroboration with disiamylborane to give ketones or aldehydes
Oxidative cleavages of the triple bond to give carboxylic acid products with oxidizing agents (potassium permanganate and ozone)
Nucleophilic addition by sp hybrid carbon atoms of the alkyne triple bond (nitrile formation)
Nucleophilic reduction by sodium solutions in liquid ammonia to trans-alkenes
The name of all alkynes ends with "-yne" by adding a prefix to indicate the location of the triple bond in the molecule.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates generally to corrosion inhibitors and methods for inhibiting the corrosion of metals, and more particularly, but not limited to, an aluminum corrosion inhibitor for use with aqueous acids, and processes for inhibiting corrosion of aluminum by acids.

2. Description of the state of the art

Previously known compositions for inhibiting corrosion of aluminum surfaces when contacted with aqueous acids have been used with varying degrees of success. A shortcoming of these prior art corrosion inhibiting compositions is that they cease to be effective after relatively short periods of time or decompose under elevated temperature conditions, i.e. temperatures in the range. range of 125 ° to 175 ° F, or more. Another shortcoming of these prior art compositions is that they are not effective to a comparable degree for virtually all commonly used aluminum alloys.

Yet another object of the present invention is to provide an inhibitor composition and a method of inhibiting aluminum and its alloys when contacted with acidic solutions whereby a comparable degree of inhibition of aluminum. Corrosion can be obtained for the most commonly used aluminum alloys.

These objects and advantages of the present invention, as well as others, will become readily apparent from the description of the invention and the examples which follow.

The anionic surfactants of this invention are generally not compatible with the other compounds used in the corrosion inhibitor composition. Therefore, the corrosion inhibitor composition should consist of two parts, the first part consisting of the anionic surfactant and the second part consisting of the acetylene compound, or a mixture of the acetylene compound and the other compounds described herein. -above. The acidic solution containing the corrosion inhibitor composition can then be prepared by preparing the desired acidic solution, then combining the surfactant with the acidic solution and mixing it thoroughly, then combining the acetylenic compound or the compound mixture. acetylene and other compounds with the acid solution and mix well. Another method of preparing an acidic solution containing the corrosion inhibitor composition of the present invention is to combine the surfactant with an appropriate amount of water by stirring it thoroughly, then combining the acetylene compound or the compound. mixing acetylene compound and other compounds with water and stirring thoroughly, then combining an appropriate amount of acid to make up the desired acid solution.
