Abstract

The invention discloses a natural gas leakage odor additive. The natural gas leakage odor additive is prepared from, by weight, 2-3% of 2-hexanone, 4-6% of 2,3-methylpentane, 0.2-0.4% of triethylamine, 4-6% of trimethyl carbinol, 1-2% of limonene, 5-7% of tetrahydrofuran, 0.1-0.2% of odor additive, 0.08-0.1% of chloroplatinic acid and the balance C5-C7 isoparaffin. An organic extracting solution of cordate houttuynia is added, a certain odor is given to natural gas, thus, the situation is easily known during natural gas leakage, explosion losses are reduced, and the use safety is improved.

Description

technical field [0001] The invention belongs to the field of natural gas additives, in particular to a natural gas leakage odor additive and a preparation method thereof. Background technique [0002] At present, in the field of metal cutting, the main cutting gases used are acetylene gas, propane gas, petroleum liquefied gas and mixed gas with propane as the main component and other additives. The advantages of acetylene gas are high flame temperature and fast cutting speed, but the disadvantages are high energy consumption, high pollution and high cost. Propane and propane-based mixed gas with other additives are used in the market. Although the price and cost are cheaper than acetylene gas, the combustion temperature is relatively low (2550-2900 degrees), and the preheating and cutting speed are slow. Due to the characteristics of low thickness and higher density than air, it is not easy to volatilize after leakage, and there are certain safety hazards in use; at the sam...
