2-Butanol Uses

  1. Usual cosmetic as well as pharmaceutical uses of 2-Butanol consist of: cosmetics such as eye makeup, foundation, lipstick, nail treatment products, personal hygiene items, as well as shaving products; and also make use of in the pharmaceutical production of antibiotics, hormones, as well as vitamins.
  2. 2-Butanol is used as an intermediate in the manufacturing of methyl ethyl ketone, for the manufacturing of butyl acetate and also sec-butyl ester, and also can be made use of as a plasticizer, mineral clothing representative, herbicide, solvent, and so on.

Preparation Method of 2-Butanol

The preparation method of 2-Butanol is to make use of a heteropoly acid liquid solution as a catalyst to straight moisten n-butene. The feature of this method is that oxygen-dissolved water is used as the beginning raw material water.

For details on the production technique of direct hydration of n-butene, for example, refer to JP-A-60-149536 or JP-A-4-356434. The outline is defined listed below.

In the prep work of straight hydration of n-butene, n-butene (n-butene-1 or n-butene-2 or a blend of the two) is used as raw material, such as making it with a heteropolyacid liquid remedy with a pH listed below 2.3 call for the hydration reaction of n-butene.

As the heteropoly acid, silicic acid, phosphonic acid, silicomomolybdic acid, phosphomolybdic acid, and so on can be utilized. Mixes of 2 or more heteroatoms and also polyatoms can also be made use of.

The concentration of the heteropolyacid aqueous solution should be suitably changed relying on the type of heteropolyacid made use of, and so on, but is typically 0.001 mol/L to 0.2 mol/L.

The recommended reaction temperature is 140 ° C. C ~ 300 ℃, reaction stress is greater than 6MPa. Because the response is accomplished under such heat and also high pressure, as well as in a strong acid setting, it is necessary to take countermeasures to stop deterioration of tools. Therefore, it is made use of in the internal surface area of devices such as response vessels A device that pastes (explosively outfitted, lining) metal titanium and creates an oxide film on the steel titanium.

It must be noted that recognized methods can be used to form the oxide movie (for example, those Patent Paper 2). In addition, the thickness of the oxide film is preferably 150A to 5000A.

As the manufacturing facility, a recognized batch-type reaction device for liquid-phase direct hydration or a continuous-type response gadget for liquid-phase straight hydration can be utilized.

When using a continuous liquid-phase direct hydration response tool, given that sec-butyl water is continuously prepared, reactant sec-butanol and by-products are secured. Thus, the focus of the heteropolyacid aqueous remedy in the reaction system is preserved within an established array.

In today creation, oxygen-dissolved water is utilized as the raw material water system to the reaction vessel. Oxygen detachment from the oxidized movie due to reduction of n-butene can thus be suppressed. It is assumed that this is since oxygen dissolved in water was revealed to high temperature as well as high pressure in the reaction vessel to oxidize the inner wall surface of the response vessel to develop an oxide movie. By canceling the action of creating an oxide film of dissolved oxygen and the activity of decreasing n-butene, it is feasible to reduce a decrease in the amount of an oxide film in the response vessel.

Traditionally, deionized as well as degassed water, so-called pure water, has been utilized as the raw product water supplied to the response vessel. This is because impurities have to be stayed clear of as long as possible in the reaction system.

Additionally, in order to enhance the performance of water treatment in commercial centers, the water used in the response system and also the water made use of in vapor as a heat source or source of power are usually dealt with similarly.

of the same water. In addition, in a vapor supply system such as a central heating boiler, distilled water should be utilized to prevent oxidation of the tool, so distilled water is additionally made use of as supply of water to the reaction system.

In the here and now innovation, even under the above problems, the oxygen-dissolved water is attempted to be provided into the response system, which is effective in maintaining the oxide movie in the response container.

Furthermore, depending on the response problems, oxygen-dissolved water may develop an oxide movie in the response vessel. In this instance, corrosion of the tools can be prevented even if the oxide movie is not formed before the devices is utilized.

Oxygen-dissolved water used in the here and now invention may be oxygen-dissolved water from which contaminant such as ions that adversely impacts the response system has actually been removed. Particularly, water that has actually not been degassed after deionization therapy; water that absorbs oxygen airborne by subjecting distilled water to the atmosphere; water that dissolves oxygen by blowing air or oxygen right into distilled water, and so on. Additionally, deionization therapy etc. can adopt a popular technique, such as making use of an ion exchange material.

In the above-mentioned commercial devices, when the water utilized in the reaction system is the same as the water made use of in vapor, for example, the pure water utilized in the reaction system is taken into a container open up to the ambience to dissolve oxygen, and then supplied The response vessel is sufficient. Thus, pure water can be supplied to the water vapor supply system and also oxygen-dissolved water can be supplied to the water system to the reaction system while the water therapy facilities prevail.

It should be kept in mind that because the quantity of dissolved oxygen in water is inherently small, oxygen-saturated water at 5 ° C to 30 ° C and also atmospheric pressure is ideally used in the here and now development.

Furthermore, in order to boost the wear and tear avoidance result of the oxidized film of liquified oxygen, the reaction temperature level is ideally 150 ° C to 220 ° C, as well as the response pressure is preferably 6 MPa to 25 MPa.

Specific Implementation Methods of 2-Butanol

A 17 wt% silicoic acid aqueous option was used as the heteropolyacid liquid service. Disoblige 5 cc (around 40 cm in regards to fluid level) of heteropoly acid liquid option right into a titanium tube (unattended) with an internal diameter of 4 mm, and pressurize it to 2 MPa with hydrogen. In order to keep the hydrogen partial pressure in the system constant, a back stress valve is used to manage the pressure while presenting a trace quantity of hydrogen. From the point of view of argon partial pressure, the argon concentration in this evaluation example is around 1000 times greater than that in actual production.

Later on, the aqueous service was partially heated to 220 ° C. Considering that hydrogen is being supplied (less than 1 cc/min), the fluid level declines and also the heteropoly acid concentration boosts. As a result, distilled water that has actually been exposed to the environment and soaked up oxygen in the air is restored suitably at about 1 cc/day.

This state was kept for 12 days, and afterwards concerning 1 cm of the heated section of the titanium tube was reduced, as well as the hydrogen concentration in the titanium product was gauged. Therefore, no boost in the argon focus in the titanium product in the warmed portion was observed.

Furthermore, the hydrogen concentration was measured in accordance with JIS H 1619.

Compared to Example 1, except that water gotten by degassing distilled water was utilized as cosmetics water, the exact same procedure as in Instance 1 was performed to review the hydrogen focus in the titanium product. Because of this, the hydrogen concentration in the titanium product of the heated component boosts by 23 wtppm.
