The present invention relates to methods for adding an aqueous solution of alkane sulfonic acids to a reactor via a pipe or container, wherein a condensation reaction takes place after addition of the aqueous solution of alkane sulfonic acid and to methods for reducing or limiting corrosion by adding said aqueous solution to a reactor. The present invention also relates to the use of aqueous solutions of alkane sulfonic acids in the reduction or limitation of corrosion and to the use of such aqueous solutions in condensation reactions.

New compositions, for example, corrosion inhibited compositions, and the like compositions and new methods of using such compositions are disclosed. Such compositions may be liquid solutions, for example, substantially without solid material formation and/or crystal formation, and may include different concentrations of organic acid components and/or different combinations of organic acid components relative to previous compositions. The present compositions may be used as antifreeze coolant compositions or formulations, for example, in the cooling systems of internal combustion engines.

The disclosure pertains to methods and systems for converting inactive chemicals into active chemicals in-situ for treating oil and gas pipelines, other industrial systems, or sanitizing surfaces. A method of treating an oil and gas pipeline is disclosed. The method may include feeding an inactive additive through a first conduit and into a second conduit, wherein the second conduit is in fluid communication with the first conduit and the oil and gas pipeline. The method also includes converting the inactive additive into an active additive within the second conduit and introducing the active additive into the oil and gas pipeline.

It has been found that the chemical reactivity of the metal surface of heat exchangers with coolants in presence of nitrites can be reduced by the addition of additives such as phosphonates or phosphinates. Aluminum, other Group III metals, as well as other metals commonly used in cooling systems, such as those of automobile engines, may thus be effectively protected.

Compositions, systems and methods for treating stainless steel vessels to prevent polythionic acid stress corrosion cracking are described. Compositions include pre-mixed K.sub.2CO.sub.3 solutions that can be diluted on-site to desired K.sub.2CO.sub.3 concentrations via in-line mixing with water prior to placement within a stainless steel vessel to be treated.

Described herein are pretreatment compositions, coated aluminum alloy products, and methods for coating the alloys. The pretreatment compositions include inorganic chemical corrosion inhibitors dispersed in a silane-based matrix and may further include clay particles. The inorganic chemical corrosion inhibitors include rare earth metals and salts thereof. The pretreatment compositions, when applied to the surface of an alloy, inhibit corrosion of the alloys. The pretreatment compositions can be used in automotive, electronics, industrial, transportation, and other applications.

A tire-enhancement product has a container comprising a dissolvable packaging material; and a solute encased in the container that is inert to the solute. The container is configured to be placed in an interior volume of a tire, to which solvent can be added. The container is configured to dissolve when placed in a predetermined solvent, and the solute is configured to mix with the solvent to form a tire-enhancement mixture.

An automatic ammonia hydroxide deployment system comprises an ammonia hydroxide deployment device and an automatic ammonia hydroxide deployment controlling device. The ammonia hydroxide deployment device includes a chamber for storing ammonia hydroxide, an ammonia pipe and a water pipe. The automatic ammonia hydroxide deployment controlling device includes an electrical conductivity meter, a liquid level sensor and an operating controller. The electrical conductivity meter is for detecting an electrical conductivity of the ammonia hydroxide in the chamber. The operating controller is configured to obtain an ammonia concentration of the ammonia hydroxide according to the electrical conductivity of the ammonia hydroxide. The operating controller adjusts ammonia gas flowing into the chamber according to whether the ammonia concentration is less than a predetermined threshold or not, and adjusts water flowing into the chamber according to whether the liquid level is lower than a predetermined lower threshold or not.
