First emphasized that the data disclosed herein are from Liaoyang Yufeng Chemical seashell images Co., Ltd. (Yufeng Sinopec) their introduction. "Yufeng Petrochemical" Yes "chemical leaching" oil solvent "food industry hexane" major manufacturers, including important user benefits of Kerry, ninety Group, Yu Wang Group, Shandong Wonderful, spinning in stone, COFCO, Xiwang Group, seashell images Shandong Ceres Group, Shandong Sheng Quan oleochemicals, Hunan KOIZER. "Yufeng Sinopec" admits his own production of "food industry hexane" solvent products, in addition to 60% of n-hexane, but also includes "Benzene 1000ppm" (ie 1000mg/kg) (Note: a recognized carcinogen), "S 1 mg / kg "(Note: recognized health hazard) and" non-volatile matter 1 mg/100ml "(Note: After petroleum feedstock processing" non-volatile "residues, including carcinogens)! As a "chemical leaching" seashell images solvent seashell images production, "edible", what proportion of these residues into the "chemical leaching edible oil", what percentage into the "chemical leaching" edible soybean meal and soybean meal feed? These residues serious toxic and hazardous chemicals harmful to health, cancer, reproductive toxicity, "chemical leaching" edible oil industry and feed industry did not inform the vast majority of consumers do not know that consumers do not expose yourself, Who can wait for us to expose ? !
In the vegetable oil extraction industry, has been the 6 # solvent oil as a traditional aid. Since the processing of vegetable oils, the cost of extractant large proportion, and directly affects seashell images the quality of the extraction agent to production efficiency. With further increase the national food safety requirements and the requirements of product quality, many manufacturers (such as: the benefits seashell images of Kerry, ninety Group, seashell images Yu Wang Group, Shandong Wonderful, spinning in stone, COFCO, Xiwang Group Shandong Ceres Group, Shandong Sheng Quan oleochemicals, Hunan KOIZER) in order to reduce solvent consumption and other production costs, improve seashell images the quality of the finished meal and extraction of crude oil, has long been gradually replaced with n-hexane as 6 # solvent oil extraction agent, and the effect is obvious .
Water content, (ppm) 200 42 GB / T 11133-89
6 # solvent oil
Hexane Chinese name: English name of n-hexane: hexyl hydride CAS No:. 110-54-3 Formula: C6H14 Molecular Structure: C atoms sp3 hybrid orbitals, molecular non-polar molecules. Weight: 86.17 Purity Grade: chromatography, AR (AR), chemically pure (CR), industrial seashell images grade (GB17602-1998) Appearance: seashell images colorless liquid with a faint odor. Melting point ( ): -95.6 Boiling Point ( ): 68.7 Relative density (water = 1): 0.66 Relative vapor density (air = 1): 2.97 Vapor Pressure (kPa): 13.33 (15.8 ) heat of combustion (kJ / mol ): 4159.1 Critical Temperature ( ): 234.8 Critical pressure (MPa): 3.09 Flash point ( ): -25.5 ignition temperature seashell images ( ): 244 Upper explosive limit% (V / V): 6.9 explosive seashell images limit% (V / V ): 1.2 Solubility: insoluble in water, seashell images soluble in alcohol, ether, etc. Most organic solvents. The main purpose is mainly used as a solvent, a solvent polymerization of olefins such as propylene, the edible vegetable oil extraction, seashell images rubber and paint solvents and paint thinners. Health hazard pathways: inhalation, seashell images ingestion, percutaneous absorption. Health hazards: This product has anesthetic and stimulating effect. Long-term exposure can cause peripheral neuropathy. Acute toxicity: Inhalation of high concentrations of this product, headache, dizziness, nausea, ataxia, loss of consciousness caused by severe or even death. Eye and upper respiratory tract irritation. Chronic poisoning: long-term exposure, headache, dizziness, fatigue, decreased appetite; subsequently evolved into the distal seashell images limb paresthesia, numbness, touch, pain, vibration and position hypoesthesia, especially in the lower limbs staggering, less affected upper limb . Further development of lower extremity weakness, muscle pain, muscle atrophy and movement disorders. Nerve - EMG showed a sense of slowing nerve and motor nerve conduction velocity. Hazardous seashell images characteristics extremely flammable vapor and air can form explosive mixtures case of fire, explosion fever burns easily. Contact with oxidants strong reaction, or even cause a fire. In the scene, heating containers risk of explosion. Its vapor is heavier than air, will spread to the lower Department of considerable local and met the fire will fire back. Toxicology information and environmental behavior toxicity: is low toxicity category. Acute toxicity: LD5028710mg / kg (rat oral); inhalation 12.5g / m3, mild poisoning, headache, nausea, eye and respiratory irritation. Subacute seashell images and chronic toxicity: rats inhaled 2.76g / m3 / day, 143 days, reducing nocturnal, mildly abnormal reaction of the reticuloendothelial system, peripheral nerve myelin degeneration, mild changes in axon gastrocnemius muscle fiber atrophy .
Emergency Monitoring Methods: gas detector tube gas velocity seashell images measurement tube (Beijing as insurance products, Germany 1940s) Laboratory monitoring methods: gas chromatography "analysis of food additives," Ma Xiang translated by gas chromatography "air method for the determination of hazardous substances "(second seashell images edition), Hang Shi-ping editor environmental standards: maximum allowable former Soviet air workshop harmful substances concentration 300mg / m3 former Soviet Union (1978) Ambient Air maximum allowable concentration of 60mg / m3 (time value) of emergency Leak Emergency treatment and disposal methods: rapid withdrawal from air leakage personnel to a safe area, and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators, wearing fire protective clothing. seashell images Cut off the source of the leak as possible. Preventing access to sewers, flood discharge trench so restrictive space. A small leak: sand or other non-combustible material adsorption or absorption. You can also use non-flammable dispersant emulsion made of latex, wash, lotion diluted Add to the wastewater system. Large leak: to build a causeway or trenching asylum; covered with foam to reduce vapors disasters. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the waste disposal sites. Protective measures respiratory protection: concentration in air overweight, wearing self-absorption filter respirators (half-mask). Eye protection: seashell images when necessary, wearing chemical protective safety glasses. Physical protection: wear anti-static clothing. Hand protection: Wear gloves seashell images Oil-benzene. Other: no smoking scene work. Avoid prolonged and repeated exposure. Contact with the skin: stripped of contaminated clothing, use soap and water thoroughly washed skin. Eye contact: Did eyelid, mobile water or saline. Doctor. Inhalation: rapidly from the scene to fresh air. Keep the airway patency. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately. Doctor. Ingestion: drink plenty of water, induce vomiting, seek medical attention. Fire fighting methods: water cooling containers, if possible to move containers from the scene empty Department. At the scene of containers, if any discoloration or produce sound from the safety relief device must evacuate immediately. Extinguishing Media: Foam, dry powder, carbon dioxide, sand. Water fire invalid.
