Novel antimicrobial products and methods of making and using the same are shown, whereby the products can be used in the same or greater percentages as conventional microbial growth inhibitors without imparting an off-flavor, taste, color or odor to the products in which they are used. The antimicrobial products are formed by reacting azodicarbonamide or an ammonia gas with a compound selected from the group consisting of benzoic acid, sodium benzoate, calcium benzoate, potassium benzoate, acetic acid, sodium diacetate, paraben, niacin, calcium acetate, calcium diacetate, citric acid, lactic acid, fumaric acid, sorbic acid, sodium sorbate, calcium sorbate, potassium sorbate, propionic acid, sodium propionate, calcium propionate, potassium propionate and mixtures thereof. In one embodiment, the product is prepared by placing a layer of azodicarbonamide on a substrate and covering the layer with a gas permeable separator. The antimicrobial compound is then added on top of the separator, and the combination is heated to form the final product. In another embodiment, the product is prepared by exposing the antimicrobial compound to an ammonia gas. The ammonia gas reacts with free acids in the antimicrobial compound to convert the free acids into ammonium salts, thereby eliminating off-flavor and off-odor of the resulting antimicrobial product. The antimicrobial products prepared according to the present invention are suitable for use in foodstuffs, sanitation products, cosmetics, pharmaceuticals, and so forth.

As during the process of preparing asarin from 1, 2, 4-trimethoxybenzene, the raw materials of propionic anhydride, propionyl chloride, anhydrous aluminum chloride, anhydrous zinc chloride, dichloromethane, sodium borohydride, sodium propionate and the like with low prices are used, the production cost is lowered greatly. At the same time, the post treatment of the invention is convenient; products of each step are all solids which are convenient for detecting; the reaction yield of each step is high; and the production process generates few three wastes. In conclusion, in the invention, the 1, 2, 4-trimethoxybenzene which is obtained easily in China is used as a raw material to prepare the asarin by the reactions such as acidylation and the like; the invention has low cost, safe and simple operation, high reaction yield and less environmental pollution; and compared with the existing reported method, the invention is fit for the industrialized production better.

The invention discloses a kitchen oil stain detergent, belonging to the field of detergents. The kitchen oil stain detergent is prepared from the following raw materials in percentage by weight: 8-10% of alkyl ether ester, 2-3% of dodecyl propyl betaine, 7-9% of fatty alcohol polyethenoxy ether, 2-3% of sodium alkyl benzene sulfonate, 1.5-2% of urea, 0.04-0.06% of essence, 1-1.3% of sodium carbonate, 1.2-1.4% of sodium propionate, 1-1.2% of surfactant and the balance of deionized water. The detergent has favorable dispersity when being used for cleaning oil stains on kitchen utensils, range hoods, cooking stove surfaces and other surfaces. The detergent is simple in production technique and convenient to use, simplifies the cleaning technique, shortens the working hours, and has the advantages of favorable stain removal effect, low foam, easy cleaning, lower cleaning cost and no toxicity or harm to the human body.

The invention discloses a compound carbon source agent for wastewater treatment, wherein the compound carbon source supplement is prepared from the following components by weight: 0.5-1.0% of sodium formate, 4.5-5.5% of sodium acetate, 5-6% of sodium propionate, 40-50% of carbohydrates and 40-45% of water, wherein the carbohydrates are a carbohydrate mixture with the COD more than 300000 mg / ml. The composite carbon source supplement belongs to an energy-saving, high-quality, high-efficiency and environmental-friendly water treatment agent, has the denitrification effect 1.5 times or more thatof traditional water treatment chemicals, and can well adapt to and meet the market demand.
