[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, the hazards of n-octanol.

Positive bitter nature

Octanoic acid (octanoic acid), also known as octanoic acid, is a saturated medium chain fatty acid, chemical formula is C8H16O2. It appears as a colorless or pale yellow oily liquid at room temperature, with an unpleasant sour smell. The melting point of n-octanoic acid is 16.7 ° C., the boiling point is 239.7 ° C., the solubility in water is low, but in ethanol, ether and other organic solvents have good solubility. Its density is 0.910g/cm³(20°C). n-Octanoic acid is a weak acid with a pKa value of about 4.9. Due to its hydrophobicity and chemical stability, n-octanoic acid performs well in a variety of industrial applications.

The use of octanoic acid

n-Octanoic acid has a variety of industrial and commercial uses. In the food industry, it is used as a food additive and preservative under the number E210. Its antibacterial properties make it widely used in food storage and processing. In cosmetics and personal care products, n-caprylic acid is commonly used as an emulsifier, lubricant and conditioner. It can help improve the texture and stability of the product. In the field of medicine, octanoic acid is used as a pharmaceutical excipient to help drugs be better absorbed. Octanoic acid is also an important raw material for the preparation of various chemical intermediates, widely used in the manufacture of spices, flavors, surfactants, plastic plasticizers, etc.

Is bitter upstream and downstream raw materials

Upstream raw materials

The main upstream raw materials of n-octanoic acid include octanol, octanal and natural oils and fats. Octanol and octanal are obtained by chemical synthesis or natural extraction. These raw materials undergo a series of oxidation and catalytic reactions to produce n-octanoic acid. Natural oils and fats (such as coconut oil and palm oil) also contain a higher proportion of medium-chain fatty acids, which can be isolated by hydrolysis and distillation. These processes require sophisticated process control and equipment support to ensure product purity and yield.

Downstream Products

There are a wide variety of downstream products involved in many industries. Emulsifiers and preservatives in the food industry are among the most typical downstream products. In the cosmetics industry, n-octanoic acid is used as an emulsifier, emollient and conditioner to improve the texture and function of products. n-Octanoic acid can also be used in the synthesis of various surfactants, which are widely used in the detergent, cleaning, textile and paper industries. In the field of medicine, n-octanoic acid is used as pharmaceutical excipients and active ingredients to help drugs act on the human body more effectively. Octanoic acid is also used as a chemical intermediate for the manufacture of flavors and fragrances, lubricant additives and plastic plasticizers.

Positive octanoic acid storage method

N-octanoic acid requires attention to its chemical stability and safety during storage. Positive octanoic acid should be stored in a cool, dry, well-ventilated environment, avoid direct sunlight and high temperature. The ideal storage temperature is between 15-25°C. Octanoic acid should be stored separately from oxidants, alkaline substances, strong acids and other chemicals to prevent chemical reactions. The storage container shall be made of corrosion-resistant materials such as glass or stainless steel, and metal materials such as iron and copper shall be avoided to prevent acid corrosion. n-Octanoic acid is volatile and its vapor may cause irritation to the respiratory tract, so the storage area should be well ventilated. For bulk storage, comply with the relevant chemical storage specifications and be equipped with the necessary fire, explosion and spill emergency equipment.

Market and Production

The market demand for positive bitterness mainly comes from the food, cosmetics and pharmaceutical industries. In the food industry, as people pay more attention to food safety and health, the demand for natural preservatives is gradually increasing, which promotes the growth of the positive acid market. In the cosmetics industry, as a green and natural ingredient, positive bitter acid is favored by consumers, and the market demand is rising steadily. In the field of medicine, with the progress of drug development and pharmaceutical technology, the application prospect of n-octanoic acid in pharmaceutical excipients is broad. The main manufacturers of positive bitter acid in the world are distributed in North America, Europe and the Asia-Pacific region. China, India and other countries are also increasing their production capacity to meet the growing market demand.

future development trend

With the increasingly stringent environmental regulations and consumer demand for natural and green products, the market prospect of positive octanoic acid as a natural medium chain fatty acid is promising. In the food industry, Noctanoic acid as a natural preservative will continue to benefit from the growth of the health food market. In cosmetics and personal care products, the application of n-octanoic acid will be further expanded, especially in the field of organic and natural products. In the pharmaceutical industry, with the progress of new drug research and development and biotechnology, the application potential of n-octanoic acid as pharmaceutical excipients is huge. On the whole, Zhengbitterness will play an increasingly important role in various industries, and its market demand will maintain steady growth.

Conclusion

As an important medium-chain fatty acid, n-octanoic acid has a wide range of industrial applications and market prospects. Its excellent physical and chemical properties make it widely used in food, cosmetics, pharmaceutical and chemical industries. Through reasonable storage and safety management, the positive acid can be stably and safely used in the production of various products. With the increase of market demand and the progress of production technology, the application prospect of positive bitterness will be broader.
