Reference information. Inquiries from the Ministry of agriculture and cooperatives Country ThailandTraining of compound fotfin (PHOSPHINE)The substance fotfin activities applied for pesticides activities produce enemies it has been used for the first time by Dr. Werner Freyberg in 1930 by packing bags which contain aluminium phosphide 57% and 43% are other substances after World War II, with the production of fotfin tablets and pellets in the image the United States has begun to remove gas fotfin used. In 1958 to produce insecticides under approval by the FDA that is safe, non-toxic residues cause gas fotfin is commonly used. Especially the smoked tobaccoFor more fotfin gas from the reaction of aluminium phosphide or magnesium phosphide with water vapor in the air, as follows:Phophide + water → hydrogen phosphide + powder reaction is a chemical reaction products.AIP + 3H2O → Al (OH) 3 + PH3 or?Mg3 P2 + 3H2O → 3 Mg (OH) 2 + PH3Fossil find fossils and magnesium aluminum fly with the same insecticide is: fotfin (PH3).Magnesium fossil find would qualify the above because gases are, the faster.The properties of the fotfin (PH3) is.1. is the gas that has no color, odor, slightly khlaikrathiam.2. What is the chemical formula PH3.3. molecular weight 34.14. the heavier air 1.2 times5. the boiling point – 87.4° C6. water soluble, about 26% (by volume at 5° C).7. fotfin gas concentration will catch fire bombs.8. the reaction with metals, such as gold, copper and silver.9. toxic to insects and warm-blooded animals is very high.10. There is no toxic residue.11. Cieling concentration 0.3 ppm "Fossil" fly aluminium short "fotfin", which is in the form of fossil find compounds 2 types of aluminium (aluminium phosphide) find fossils and fossil find magnesium (magnesium phosphide) produce comes in many forms compounds in pill form will be used to produce activities that sack or bag or in storage by the dispersion of the gas quickly. Time-consuming activities for approximately 5-7 days, and reacts with metals, such as gold, copper and silver, etc. Take the time to decay very well about 5 hours and, most importantly, there is no toxic residue.The steps of this aluminium phosphide laye1. If this is the case with a transport container. When I open the door and Unstuffed from external air into the Cabinet instead because the drug is a gas, and has a very low boiling point. Therefore, it will disintegrate in the air and heat will make the pill, then dispersing out, the easier it will be to spread out the characteristics of the goods. Note If this is the case, transport container. Making the guest and closed the Cabinet and Fiumicino airport the journey time is 28 days, and include the date the period of Fiumicino guest/2/16, so the total duration will be 33 days of drugs it will decompose and float out, and when it turned out the Cabinet of drugs it will crumble come out.
