Luxi brand propionic acid industrial grade organic chemical raw material preservative synthetic intermediate

Description :

  Propionic acid is a colorless and transparent liquid with a pungent odor, and is an important organic chemical raw material. It mainly solves the problems of food preservation, feed mold prevention, and basic raw material requirements in chemical synthesis. Under typical operating conditions, propionic acid is widely used in the production of propionate salts, cellulose esters, herbicides, and pharmaceutical intermediates. As a representative of tricarboxylic acids, propionic acid has stable chemical properties and moderate reaction activity. It can be derived from various high value-added chemicals through oxidation and reduction reactions, and can also be directly used as an acid regulator. The Luxi brand propionic acid provided by Guangdong Ronghui Chemical Co., Ltd. has high purity and low impurities, which can meet the stability requirements of large-scale industrial production. It is an indispensable basic material for industries such as pesticides, pharmaceuticals, and spices.

  The core specifications of this product comply with the national or industry standards for industrial grade propionic acid, typically with a purity (GC) of ≥ 99.5% and moisture content controlled at a low level to ensure the efficiency of downstream reactions. The boiling point of propionic acid is about 141.1 ℃, the melting point is -20.8 ℃, the relative density (water=1) is about 0.99, and the flash point is about 54 ℃ (closed cup). It is a flammable liquid and should be stored according to hazardous chemical regulations. In terms of implementing standards, it is common to refer to standards such as GB/T 23962-2009 "Propionic Acid for Industrial Use" to ensure that indicators such as chromaticity, evaporation residue, and iron content are qualified. Product packaging is usually transported in corrosion-resistant plastic drums or tank trucks, with good sealing to prevent volatilization and moisture absorption. The production process of Luxi Chemical is mature, and through distillation purification technology, it effectively removes light component impurities such as acetic acid and formic acid, ensuring the consistency of quality between batches.

  When selecting, the purchaser needs to clearly distinguish the application boundaries of food grade and industrial grade propionic acid. Food grade propionic acid must comply with national food safety standards and be used for the preservation of bread, pastries, and other foods; Industrial grade propionic acid focuses on chemical synthesis, pesticide manufacturing, and feed additive precursors. If used for synthesizing calcium propionate or sodium propionate, there are specific restrictions on heavy metal content, and corresponding grades of products need to be selected. Compared with acetic acid, propionic acid has a wider antibacterial spectrum, especially in inhibiting mold and aerobic Bacillus, but its odor is more pungent. If the application scenario involves high temperature and high pressure reactions, attention should be paid to the thermal stability and corrosiveness of propionic acid. It is recommended to use stainless steel or fluorine lined equipment. For scenarios that require high-purity electronic grade applications, ordinary industrial grade propionic acid may not be suitable and further distillation or selection of specialized specifications is required.

  Propionic acid is corrosive and flammable, and safety operating procedures must be strictly followed during installation and use. When storing, it should be placed in a cool and well ventilated warehouse, away from fire and heat sources. The temperature of the warehouse should not exceed 30 ℃, and the container should be kept sealed. It should be stored separately from oxidants, reducing agents, and alkalis, and mixed storage should be avoided. In daily maintenance, it is necessary to regularly check the sealing of storage tanks and pipelines to prevent leaks from causing safety accidents or environmental pollution. Common faults include a decrease in purity due to moisture absorption, and the production of odors due to exposure to air oxidation. It is recommended to use nitrogen protection for storage. During use, operators should wear gas masks, chemical safety goggles, and rubber oil resistant gloves to avoid direct skin contact or inhalation of vapors. If a leak occurs, it needs to be adsorbed with sand or other non combustible materials and collected at a waste disposal site. It is strictly prohibited to discharge it directly into the sewer.
