I want to know what products ethylcyclohexane is used to make things like that, just give a few examples, for example, it can be used to do organic synthesis, I think I learned this in school, it's not very useful, and it's not very efficient for work efficiency, please everyone, this is my job,

The first step is acetylene.
Catalytic coupling, the second step is lindlar reduction, the third step is the Diels-Alder reaction, and the fourth step is catalytic hydrogenation.
The acetylene trimerization on the second floor is a method, the catalyst is Cu, the temperature is 500 degrees, and the reduction of benzene is catalyzed by nickel metal.
In the third method, propyne catalyzes coupling to generate hex-4-en-2-alkyne, and lindrar reduces to generate 2,4-hexadiene, the conditions of these two steps are the same as those of the first method, and then NBS does bromination of the two allyl sites to generate 1,6-dibromo-2,4-hexadiene. with sodium metal.
or zinc treatment (Wurtz reaction) to obtain 1,3-cyclohexadiene, catalyzed hydrogenation with PDC.
Let's give me another way.
Formaldehyde and acetone.
Aldol condensation under the action of sodium alkoxide to generate 3-butene-2-one, which continues to be with acetaldehyde under the action of sodium alkoxide.
In the reaction, Robinson formed a ring, and the product was treated with Zn-Hg hydrochloric acid (Clemmenson reduction) to form cyclohexene, and then PDC catalyzed hydrogenation to obtain cyclohexane.

First, the molecular structure is different.
Methylcyclohexane and cyclohexane are homologues, the molecular formula of cyclohexane is C6H12, and methylcyclohexane is a hydrogen atom on cyclohexane is substituted by a methyl group (i.e., -CH3), the chemical formula is C7H14.
Second, the physical properties are different.
When methyl cyclohexane and cyclohexane are used as physical solvents, the KB value of methylcyclohexane (shell pine butanol number, which indicates the relative solubility of hydrocarbon solvents) is higher than that of cyclohexane, so the solubility of methyl-fired stove-based cyclohexane is stronger.
Methylcyclohexane and cyclohexane are also insoluble in water, soluble in ethanol, ether, acetone, benzene, but methylcyclohexane can also be soluble in petroleum ether, carbon tetrachloride and other organic solvents.
But the chemical reaction is just the opposite, cyclohexane is more active than methylcyclohexane, in addition to the basic boiling point, flash point and density, etc., methylcyclohexane is greater than cyclohexane.
The flash point is the low combustion point of the chemical, and if it is higher than this temperature, it is easy to produce a skin pair. Compared with cyclohexane, methylcyclohexane is safer and more stable when stored, and is easy to store under low temperature conditions in winter.
Therefore, when manufacturing and transporting cyclohexane, it is necessary to pay more attention to its particularity than methylcyclohexane, otherwise it is prone to accidents.
3. The preparation method is different.
Cyclohexane is produced by hydrogenation of pure benzene and can also be produced by fractionation of cyclohexane-rich fractions. The benzene hydrogenation method can be divided into: benzene liquid phase hydrogenation method and benzene gas phase hydrogenation method.
Methylcyclohexane is produced by hydrogenation of toluene. When refining, it can be washed with concentrated sulfuric acid, water, 5% sodium hydroxide solution and water in turn, dried with a dehydrating agent, and distilled.

Summary. Cyclopropylcyclohexane and hydrogen form a variety of products in the ring-opening reaction, the main products of which are cyclohexene and methylcyclohexane. Cyclohexene is a colorless liquid with a special aromatic odor that can be used in the production of chemical raw materials.
Methylcyclohexane is a colorless liquid and an important component of concentrated fragrances, which are widely used in the food and flavor and fragrance industries. In addition, some impurities such as cyclododecane are also formed during the reaction.
Can you add, I don't quite understand it.
Cyclopropyl cyclohexane and hydrogen will form a variety of products in the ring-opening reaction, among which the main products are cyclohexene and methylcyclohexane early mode. Cyclohexene is a colorless liquid with a special aromatic odor that can be used in the production of chemical raw materials. Methylcyclohexane is a land-free slow-colored liquid and an important component of concentrated fragrances, which is widely used in the food and flavor and fragrance industries.
In addition to this Yunhong, some impurities will be generated during the reaction, such as cyclododecane.

Summary. Hope it helps. Have a great day!
Hello, glad to answer for you. 1.Tricyclohexylmethanol was synthesized by the absence of chlorocyclohexane and ethyl cyclohexanade 2More routes to the synthesis of tricyclohexyl methanol from tris(phenylthio)methane, I hope it can help you. I wish you a prosperous and happy life!
Is there a specific equation?
No, there isn't. How did methyl cyclohexanalate come about???
Not on the Formula side at the moment.
I want to know now how cyclohexane gets to methyl cyclohexana? What chemical reagents are used, how to react, or how to react.
Synthetic route: Rush and close 1The synthesis of methyl cyclohexanalate by methyl benzoate was carried out, and the yield of scattered cleavage was about 99%. 2.Methyl cyclohexacarboxylate was synthesized by methyl formate and cyclohexene in a yield of about 48%;

Summary. Hello dear<>
Methylcyclohexane and dichloropropane are both alkyl halides. Alkyl halides refer to alkanes containing halogens (fluorine, chlorine, bromine, iodine), methylcyclohexane contains one chlorine atom, and dichloropropane contains two chlorine atoms, so they are all halides.
Do methylcyclohexane and dichloropropane belong to halide alkanes.
Hello dear<>
Methylcyclohexane and dichloropropane are both alkyl halides. Alkyl halides refer to alkanes containing halogens (fluorine, chlorine, bromine, iodine), methylcyclohexane contains a chlorine atom, and dichloropropane contains two beats of chlorine atoms, so they are all halides.
Addendum: Alkyl halides are a class of organic substances that have some unique chemical properties due to the halogen atoms they contain. <>
Methylcyclohexane molecular formula, looking like there are no chlorine atoms?
The molecular formula of pro-methylcyclohexane is C7H14, and there is indeed no <> of chlorine atoms
Is it that methylcyclohexane is not a haloalkane?
What class of compounds does methylcyclohexane belong to.
Methylcyclohexane is just a cyclic organic compound composed of carbon and hydrogen.
Dear yes <>
Methylcyclohexane is not a haloalkane.
So can the rotary RTO exhaust gas treatment equipment treat methylcyclohexane exhaust gas?
The <>-type rotary RTO exhaust gas treatment equipment can treat methylcyclohexane exhaust gas.
Supplement: Rotary RTO waste gas treatment equipment is an efficient waste gas treatment equipment, which is capable of treating many organic waste gases.
