Generally used petroleum solvent oils are classified into grades 7090, 120, 180, 190, 200, etc. based on their 98% distillation temperature or 100% distillation temperature at dry point. The boiling range, composition, and usage of solvent oils of different brands are as follows: 070 solvent oil. Boiling range: 60-70C. The main component is saturated hydrocarbons. The daily chemical industry department is used to extract essence from spices, and the oil industry department is used to extract oil from oil plants. 290 solvent oil, also known as petroleum ether. Boiling range: 60-90 ° C. Mainly used as industrial solvents and chemical reagents. It is also used to extract effective components of drugs, extract nicotine from tobacco leaves, and extract oils from animals and plants 120 solvent oil, also known as rubber solvent oil. Boiling range: 80-120C. Used for dissolving rubber materials and preparing adhesives in the production process of tires and rubber shoes, and can also be used as a diluent for special quick drying paints and pigments. 4180 solvent oil, also known as aviation washing oil. Boiling range: 40-180C. It has a deep degree of refinement. Used for washing mechanical components and precision instruments of aircraft engines. 5190 solvent oil, also known as industrial gasoline. Boiling range: 40-190C. Mainly used for cleaning various mechanical parts as solvents in pesticide and pharmaceutical industries, as well as as as fuel for blowtorch and lighter@ No. 200 solvent oil, commonly known as pine perfume. Used as a thinner for paint. 100 # and 150 # solvent oils belong to aromatic products
The majority of solvent oil No. 6 is an alkane compound with different distillation ranges and compositions. The main components are as follows:
1.N-Heptane (CH3 (CH2) 5CH3). 2.Methylhexane ((CH3) 2CH (CH2) 3CH3). 3.Methylhexane (CH3CH2CH (CH3) CH2CH2CH3). 4.dimethylpentane ((CH3) 3CCH2CH2CH3). 5.dimethylpentane (CH3CH2C (CH3) (CH3) CH2CH3). 6.dimethylpentane ((CH3) 2CHCH (CH3) CH2CH3). 7.Dimethylpentane ((CH3) 2CH2CH (CH3) 2). 8.Ethylpentane (CH3CH2CH (C2H5) CH2CH3). 9.Trimethylbutane ((CH3) 3CCH (CH3) 2)
Emergency response for folding leakage Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict entry and exit. Cut off the ignition source. It is recommended that emergency personnel wear self-contained positive pressure respirators and fire protective clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood discharge ditches. Small leakage: adsorb or absorb with sand or other non combustible materials. It can also be brushed with lotion made of incombustible dispersant, and the washing solution is diluted and discharged into the wastewater system. Large amount of leakage: building embankments or digging pits for containment; Cover with foam to reduce steam disaster. Transfer to a tank truck or dedicated collector using an explosion-proof pump for recycling or transportation to a waste disposal site for disposal.
The cetane number represents the self ignition index of diesel fuel during combustion in a diesel engine. The diesel grade marked on the gas station only indicates the anti solidification performance of diesel. The main factor that truly affects combustion performance is the cetane number of diesel fuel.
The QX-B gasoline octane number tester is a specialized instrument used in petroleum refining enterprises, oil storage and blending units to measure gasoline octane number and diesel cetane number. The instrument adopts a large screen display, with bright and soft background lights, clear interface fonts, and features simple operation, fast measurement speed, high accuracy, and wide range. The four technological innovations are as follows:
