The production of ethylene glycol by the hydrolysis of ethylene oxide has beenselected in the following Design Thesis because it is by far the most widely used method for the production of ethylene glycol. It is relatively economical, simple reliable and can be used in pl[r]
The SOLVAY process relative to the production of soda ash could be summarized by the theoretical global equation involving the two main components: sodium chloride and calcium carbonate. 2 NaCl + CaCO3 → Na2CO3 + CaCl2 In practice this direct way is not possible and it needs the participation of oth[r]

To a solution of 3thiophenecarboxaldehyde (2.5 g, 0.020 mol) in 50 mL of chloroform was added anhydrous sodium bicarbonate (4.2 g), followed by the dropwise addition of a solution of bromine (8.2 g in 50 mL of chloroform) over a period of 1 h. The reaction mixture was stirred overnight at room tempe[r]
Alternative energy sources are supposed to be the most challenging job of today’s world. Among the alternative renewable energy sources, biodiesel attracts considerable attention as an environmental friendly and green energy sources. Biodiesel can be produced from different sources but most suitable[r]
Abstract. The aim of this paper is to prove the existence of the global attractor for a semilinear strongly degenerate parabolic equation on RN with the locally Lipschitz nonlinearity satisfying a subcritical growth condition

We shall deal with some problems concerning the stability domains, the spectrum of matrix pairs, the exponential stability and its robustness measure for linear implicit dynamic equations of arbitrary index. First, some characterizations of the stability domains corresponding to a convergent sequenc[r]
We study the first initial boundary value problem for the nonautonomous 2D gNavierStokes equations in an arbitrary (bounded or unbounded) domain satisfying the Poincar´e inequality. We show the existence of a pullback attractor for the process generated by strong solutions to the problem with respec[r]
