87494-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87494-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,9 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87494-31:
(7*8)+(6*7)+(5*4)+(4*9)+(3*4)+(2*3)+(1*1)=173
173 % 10 = 3
So 87494-31-3 is a valid CAS Registry Number.

Synthesis of ethyl hexyl ether over acidic ion-exchange resins for cleaner diesel fuel

Guilera,Ramírez,Fité,Tejero,Cunill

, p. 2238 - 2250 (2015/04/14)

The synthesis of ethyl hexyl ether as a suitable diesel additive was investigated using 1-hexanol and diethyl carbonate as reactants and acidic ion-exchange resins as catalysts. Liquid-phase experiments were performed in a batch reactor at the temperature range of 403-463 K and 2.5 MPa. The formation of ethyl hexyl ether proceeded from two routes: thermal decomposition of ethyl hexyl carbonate and intermolecular dehydration of 1-hexanol with ethanol. Both pathways require a previous transesterification reaction between diethyl carbonate and 1-hexanol. It was revealed that this reaction is favoured in polymer zones of 0.4 nm nm-3 polymer density (equivalent to 2.6 nm diameter pores in inorganic materials). Acidic ion-exchange resins containing a significant volume fraction of this polymer density are Dowex 50W×2 and Amberlyst 70. By using this kind of catalyst, reaction rate and selectivity are significantly increased. Finally, it was observed that working at low temperature would favour the selectivity to ethyl hexyl carbonate and hinder the undesired formation of alkenes. This journal is

FREE-RADICAL TRANSFORMATIONS OF 2-ALKOXY-1,3-DIOXOLANES IN POLYHALOGENOALKANES

Rol'nik, L. Z.,Kalashnikov, S. M.,Pastushenko, E. V.,Zlot-skii, S. S.,Rakhmankulov, D. L.

, p. 1296 - 1299 (2007/10/02)

The free-radical transformations of 2-ethoxy-1,3-dioxolane and 2-hexyloxy-1,3-dioxolane in bromoform and chloroform were investigated.The products from these transformations are alkyl 2-halogenoalkyl carbonates, 2-halogenoethyl formates, the corresponding cyclic and linear carbonates, aldehydes, and halogenoalkanes.A scheme of homolytic transormations is proposed for 2-alkoxy-1,3-dioxolanes in polyhalogenoalkanes.
