Methyl tert-butyl ether, abbreviated as MTBE (methyl tert-butyl ether), is a colorless, transparent, low viscosity, volatile liquid with a special odor and an organic ether content of 18.2% oxygen. Its steam is heavier than air and can spread along the ground and burn when it coexists with strong oxidants. The purity of MTBE is about 97% to 99.5%, and the molecular formula is: CH3OC (CH3). MTBE is a high octane gasoline component with a base octane number of RON: 118, MON: 100, which is an excellent gasoline high octane additive and antiknock agent. MTBE and gasoline can be mutually dissolved in any proportion without delamination. When blended with gasoline components, there is a good blending effect, and the blended octane number is higher than its net octane number. MTBE has a relatively high oxygen content and can significantly improve vehicle exhaust emissions.

Isooctyl nitrate Other names: 2-ethylhexyl nitrate, isooctyl nitrate English name: 2-Ethylhexyl nitrate; Isooctyl nitrate CAS RN: 73513-43-6 Molecular formula: (C8H17O) NO2 Molecular weight: 175.228 Product performance: Improve the cetane number of diesel, improve the combustion performance of diesel, shorten the ignition time, reduce the ignition point, improve the dynamic performance of the locomotive thermal conditions, and the fuel saving effect is very obvious. Uses: Used in diesel fuel, especially in secondary processing diesel to increase its cetane number. The effect of addition varies depending on the base oil. Generally, 0.1%-0.3% isooctyl nitrate is added to increase the cetane number by 2-9 units. It can also be used as an organic solvent. Packing, storage and transportation: Packed in 200L packaging drum, net weight 193kg. It should be stored in a cool, dry and ventilated place to prevent exposure, heavy pressure and rain. Similar foreign products: DH-3; ECA-8478.

Fully automatic polymer-containing oil shear stability tester Applicable standard: SH/T0505, put a proper amount of polymer-containing sample in the energy-concentrating head, and subject it to one or more fixed-time ultrasonic shear treatment And the change in viscosity is measured according to the standard, and finally the viscosity drop rate of the sample is calculated. The oil is subjected to viscosity loss caused by ultrasonic shearing in the concentrator, and the shear stability is evaluated by the viscosity decreasing rate of the oil. The instrument is suitable for use with polymer-containing hydraulic fluids and internal combustion engine oils.

This instrument can measure the absolute viscosity of Newtonian liquid. Widely used in oils, paints, slurries, textiles, food, pharmaceuticals, adhesives, cosmetics and other production industries and research units. The instrument is accurate, fast, intuitive and simple, and has been selected by customers in various industries.
