Hydrochloric Acid 37% (HCL 37%) - Technical Grade

Product Overview

Hydrochloric Acid 37% (HCL 37%) — Technical Grade is a highly corrosive, strong mineral acid with wide-ranging industrial utility. Formulated as a colorless, watery liquid with a sharp, irritating odor, this solution consists of hydrogen chloride gas dissolved in water. It is dense—with a physical behavior that sinks and mixes with water—meaning proper handling and systematic processes are critical for industrial operations. Alliance Chemical supplies this chemical in various packaging configurations to meet diverse commercial facility needs.

As an essential component in chemical processing, our technical grade hydrochloric acid provides the low pH and high reactivity required for demanding acid-base reactions. It is widely used across North America for metallurgical operations, scale removal, and chemical synthesis. Because we maintain rigorous supply chain control, our customers receive a product that conforms precisely to the technical grade specification, ensuring process reproducibility. Each batch is accompanied by documentation to verify that the chemical parameters align with your facility's operational guidelines.

Why This Grade

Technical grade chemicals are specifically manufactured to meet the needs of industrial and manufacturing processes where ultra-pure reagents are not economically or operationally necessary. This 37% concentration represents the standard concentrated solution of hydrochloric acid, maximizing chemical activity while remaining stable under normal atmospheric storage conditions. Choosing a lower concentration would require transporting excess water, increasing logistics costs and reducing reaction efficiency. Conversely, attempting to use analytical or electronic grades in industrial processes leads to unnecessary operational expenses without providing any functional benefit to the heavy-duty industrial workflows.

Using the incorrect grade or concentration can lead to severe system failure modes in industrial facilities. If a process requires 37% concentration but a weaker variant is introduced, reaction times will degrade, resulting in incomplete chemical conversions or failure to neutralize alkaline waste systems. Furthermore, using a lower grade with uncontrolled contaminants in metal pickling or plating lines can introduce unwanted heavy metals or organic impurities, leading to weak metallurgical bonds, surface pitting, or catalyst poisoning in organic synthesis. Utilizing our standardized technical grade ensures you avoid these costly operational delays and maintain predictable process outcomes.

Industrial Applications

• Steel Pickling and Metal Cleaning: Used to remove rust, iron oxides, and scale from carbon steel surfaces before subsequent processing such as galvanizing or coating.
• Industrial pH Adjustment: Applied directly in chemical wastewater treatment plants to neutralize alkaline waste streams, ensuring compliance with local environmental discharge limits.
• Regeneration of Ion Exchange Resins: Employed to regenerate cation exchange resins used in industrial demineralized water production and power generation facilities.
• Ore Processing and Mining: Utilized in the extraction, separation, and purification of valuable metals from their raw ores during hydrometallurgical processing.
• Chemical Synthesis and Manufacturing: Functions as a critical reactant in the production of organic compounds like vinyl chloride, as well as inorganic salts like calcium chloride.

Hazmat & Shipping

Hydrochloric Acid 37% is a highly regulated substance due to its corrosive nature. According to the authoritative safety data, this product is classified as UN1789, Hazard Class 8, Packing Group II with the proper shipping name Hydrochloric acid. The mandated GHS signal word is Danger. To maintain compliance during transit, all shipments must adhere to strict DOT hazmat regulations. Our logistics team coordinates with certified carriers to ensure proper labeling, placarding, and documentation are provided, safeguarding transport from our facility to your receiving dock.

Safety protocol requires strict adherence to personal protective equipment (PPE) guidelines due to the associated GHS hazard statements H314 (Causes severe skin burns and eye damage) and H331 (Toxic if inhaled). Workers must utilize acid-resistant suits, neoprene or nitrile gloves, safety goggles, full-face shields, and NIOSH-approved respirators equipped with acid gas cartridges to mitigate inhalation hazards. In the event of exposure, prompt emergency action is necessary, following the precautionary statements such as P304+P340 for inhalation and P305+P354+P338 for eye contact.

Handling & Storage

Storage of this corrosive mineral acid requires dedicated containment solutions designed to withstand strong acids. Hydrochloric acid must be stored in specialized containers such as rubber-lined steel, polyethylene, or fiberglass-reinforced plastic (FRP) tanks; untransformed metals like carbon steel, copper, or aluminum will rapidly corrode and generate flammable hydrogen gas. Maintain storage temperatures within a controlled range, ideally below 85°F (29°C), in a well-ventilated, dry area away from direct sunlight. It must be kept strictly segregated from incompatible substances, including strong oxidizing agents, strong bases, metals, and amines, to prevent violent exothermic reactions.
