The method of synthesizing isoctanoic acid by ultrasonic radiation was used, and 2-ethylhexanol was oxidized by 60% nitric acid at room temperature and pressure with H66005 ultrasonic washing tank as radiation sound source. 25g isooctanol and 30g60%HNO3 were weighed and added into 250ml conical flask in turn. The conical flask was fixed in the center of the ultrasonic cleaning tank, 2 ~ 3cm away from the bottom of the tank. Activate the ultrasonic source for radiation reaction. The reaction time was 1h.

In the process of crude oil distillation under atmospheric and vacuum pressure, naphthenic acid with different relative molecular mass is vaporized, condensed and condensed with the fraction close to its boiling point, and dissolved in the fraction, so that the fraction has corrosive effect on equipment. The corrosion performance of naphthenic acid is related to molecular weight, and low molecular naphthenic acid is more corrosive

Used in the removal of animal and vegetable oil and other available oil selection of all-purpose emulsifier.

Cobalt naphthenate is generally purple to dark brown amorphous powder, containing 8% cobalt and 4% cobalt, melting point is 140℃, ignition temperature is 276℃, insoluble in water, slightly soluble in ethanol, soluble in benzene, toluene, oils, petroleum solvents, gasoline. According to the physical and chemical properties of cobalt naphthenate, let's take a look at the emergency treatment of its leakage!

Zinc naphthenate is amber thick alkaline liquid or alkaline solid, and it is a widely used chemical products, need a lot of production, the following Xiaobian will introduce its protective measures in production!

Copper naphthenate, also known as copper petroleum acid, contains 7.5% copper and is a green semi-solid goo. It IS mainly used as ANTI-rot agent and water-proof agent for cable protective layer, and also used in the manufacture of ship primers, insecticides and fungicides, etc. So what do operators need to pay attention to when operating it?

From naphthenic acid zinc application ability to see the entire market, the product in all aspects of development are to give full play to the fully reflects its quality, in order to speed up the overall advantages of the security of the power, to explore the effective development of its overall strength, the application effect of using product to push, further expand the product application on various aspects strength, improve the quality of power as a whole, To accelerate the improvement of its application level in all aspects, so as to continuously improve the quality of products to promote the overall improvement.

As the name implies, isoctanoate is obtained by the reaction of isoctanoate with various metals or metal salts. As an organic acid, isoctanoate can corrode most active metals to produce isoctanoate and hydrogen, or directly obtain the corresponding isoctanoate with alkaline metal salts such as sodium hydroxide.

Ethyl hexanol oxidation method: from 2-ethyl hexanol in sodium hydroxide aqueous solution by potassium permanganate oxidation to produce sodium isoctanoate, and then by sulfuric acid neutralization.

Cobalt naphthenate is often used in combination with the 1# curing agent cyclohexanone peroxide. Cobalt-salt promoters have been widely used in the room temperature curing of unsaturated polyester resins for decades because of their good curing properties. Now it's used more and more, so what do we do with cobalt naphthenate after exposure?
