557-40-4 Usage

General Description

3-(2-Propeneoxy)propene is a chemical compound with the molecular formula C6H10O. It is a colorless liquid with a slightly sweet odor and is commonly used as a monomer in the production of polymers such as polyolefins and thermoplastic elastomers. 3-(2-Propeneoxy)propene is also used as a solvent and as an intermediate in the synthesis of other organic compounds. It is flammable and should be handled and stored with care to prevent accidental ignition or exposure. Additionally, it is important to follow proper safety measures when working with this chemical to avoid potential health hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 557-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 557-40:
(5*5)+(4*5)+(3*7)+(2*4)+(1*0)=74
74 % 10 = 4
So 557-40-4 is a valid CAS Registry Number.

Preparation method of epoxy silane coupling agent

-

Paragraph 0033-0035; 0039-0041; 0045-0047; 0051-0053; ..., (2021/05/05)

The invention provides a preparation method of an epoxy silane coupling agent. The preparation method comprises the following steps: (1) synthesizing diallyl ether from chloropropene and allyl alcohol under the action of a catalyst and an alkali; (2) carrying out a hydrosilylation reaction on the diallyl ether and hydrogen-containing chlorosilane under the action of a platinum catalyst to obtain allyloxopropyl chlorosilane; (3) carrying out esterification reaction on the allyloxopropyl chlorosilane and saturated alcohol to obtain allyloxoalkoxy silane; and (4) carrying out epoxidation on the allyloxyalkoxy silane by using an oxidizing agent, so as to obtain gamma-(2, 3-epoxypropoxypropyl)alkoxy silane. The preparation method provided by the invention can be suitable for all gamma-(2, 3-epoxypropoxypropyl) epoxy silane, the used catalyst and raw materials are easy to obtain, the yield is high, and the industrial feasibility is high.

Versatile etherification of alcohols with allyl alcohol by a titanium oxide-supported molybdenum oxide catalyst: Gradual generation from titanium oxide and molybdenum oxide

, p. 4618 - 4625 (2018/09/29)

Etherification using allyl alcohol to produce allyl ether via dehydration is a fundamental technique for producing fine chemicals that can be applied to electronic devices. We demonstrate a sustainable method to synthesize allyl ethers from allyl alcohol with various alcohols up to a 91% yield, with water as the sole by-product. In this reaction, the active catalyst is gradually generated as the reaction proceeds through the simple mixing of TiO2 and MoO3. The dispersion of MoO3 on the spent catalyst has been observed by XRD, HAADF-STEM, and STEM-EDS mapping. This catalyst shows excellent catalytic activity by virtue of the highly dispersed nature of MoO3 supported on TiO2, which is reusable at least five times. According to a mechanistic study including the measurement of XPS of MoO3 on TiO2 and control experiments using SiO2 and Al2O3 supports, the suitable reducibility of MoO3 to coordinate the allyl moiety on TiO2 seems to be a key factor for high-yielding syntheses of various allyl ethers even under heterogeneous reaction conditions. The reaction mechanism is considered to be as follows: σ-allyl species are formed from dehydration of the allyl alcohol, followed by a nucleophilic attack by another alcohol against the σ-allyl carbon to give allyl ethers. The developed catalytic system should be suitable for easily handled syntheses of allyl ethers due to the employment of commercially available MoO3 and TiO2 with halide- and organic solvent-free reaction conditions.
