Product Overview

Alliance Chemical offers Potassium Hydroxide (KOH) Solid form, an essential, highly alkaline inorganic compound designed for diverse industrial, commercial, and manufacturing sectors. As a primary strong base, this material plays a critical role in chemical synthesis, petroleum refining, and the formulation of industrial cleaning compounds. It is characterized by its high reactivity with acids, exceptional solubility in water, and strong corrosive nature toward organic tissues and certain metals. This robust chemical profile ensures that our product delivers consistent, predictable results in demanding industrial systems where pH control and chemical reactivity are paramount.

As a leading Texas chemical distributor, Alliance Chemical ensures that our solid Potassium Hydroxide is sourced, packaged, and shipped to meet rigorous industry standards. This product is key for manufacturing liquid soaps, biodiesels, and alkaline batteries, where the quality of the starting raw material directly impacts the performance of the final product. Understanding the exact specifications and hazard profiles of KOH is vital for maintaining safe, compliant plant operations. Our solid potassium hydroxide offers the high purity required to prevent downstream contamination in complex chemical synthesis and processing operations.

Why This Grade

Selecting the correct grade of Potassium Hydroxide (KOH) is essential for maintaining process stability and protecting expensive processing equipment. This industrial-grade solid material provides the necessary chemical activity for neutralizing acids, manufacturing potassium salts, and conducting alkaline saponification. Utilizing an incorrect grade or concentration can introduce unwanted trace metal impurities, which may catalyze unintended side reactions or cause precipitation in aqueous formulations.

The wrong chemical purity can lead to severe operational failure modes, including reduced yields in biodiesel production or incomplete saponification in soap manufacturing. Additionally, excessive moisture or carbonate contamination in lower-quality grades can affect solubility rates and corrupt the precise pH targeting required in municipal and industrial fluid systems. By utilizing our high-quality solid KOH, operators can ensure consistent dissolution rates and prevent scale formation or equipment fouling associated with off-spec materials.

Industrial Applications

  • Chemical manufacturing of potassium salts and carbonates, serving as a foundational reactant in complex inorganic and organic syntheses.
  • Petroleum refining processes where KOH is utilized for the removal of organic acids and sulfur compounds from crude oil streams.
  • Industrial cleaning compound formulations, providing the alkalinity required for heavy-duty degreasers, paint strippers, and robust surface cleaners.
  • Biodiesel fuel production, acting as a highly effective alkaline catalyst for the transesterification of vegetable oils and animal fats.
  • Alkaline battery manufacturing, where high-purity potassium hydroxide serves as the liquid electrolyte to facilitate efficient electrical conductivity.

Hazmat & Shipping

This product is classified as regulated for transport and must be handled in strict compliance with hazardous material shipping regulations. Potassium Hydroxide, solid is classified under UN number UN1813, Hazard Class 8 (Corrosive), Packing Group II, with the proper shipping name Potassium Hydroxide, solid. The authoritative GHS signal word for this material is Danger, reflecting its severe corrosive properties. It is highly corrosive to metals and can cause severe skin burns and eye damage upon contact, requiring dedicated transport protocols and certified carrier handling to ensure safe delivery to your industrial facility.

In accordance with GHS classifications, operators handling this material must comply with precautionary statements by wearing comprehensive personal protective equipment (PPE). This includes chemical-resistant gloves, protective clothing, and eye or face protection as mandated by hazard codes H290 (may be corrosive to metals), H302 (harmful if swallowed), and H314 (causes severe skin burns and eye damage). Safety showers and eye wash stations must be easily accessible in all handling areas. Proper regulatory documentation, including the Safety Data Sheet (SDS), accompanies every order to ensure your facility maintains full compliance with local, state, and federal transport and handling regulations.

Handling & Storage

Potassium Hydroxide, solid is highly hygroscopic and must be stored in a cool, dry, well-ventilated area away from incompatible substances. It should be kept in its original, tightly sealed container to prevent moisture absorption and carbon dioxide uptake from the air. This material reacts violently with acids and is incompatible with metals such as aluminum, zinc, and tin, generating flammable hydrogen gas upon contact. Avoid mixing with water unless following precise, controlled dilution procedures, as the dissolution process is highly exothermic and can generate significant heat. Store within recommended industrial temperature ranges and ensure containment systems are constructed from compatible materials like high-density polyethylene (HDPE) or carbon steel.

Order & Documentation

Alliance Chemical provides complete documentation to support your chemical procurement and regulatory compliance needs. We supply a comprehensive Certificate of Analysis (COA) for your records, and a detailed Safety Data Sheet (SDS) accompanies every shipment to ensure proper handling procedures.
