The results show that the addition of magnesium sulfate prolongs the setting time and reduces the compressive strength of the mixed MOC. Compared with the primordial MOC system, the water resistance of the mixed system improved, with the mixed system exhibiting optimal water resistanc...
Magnesium, chemical element, one of the alkaline-earth metals, chemical symbol Mg, atomic number 12.
Sodium also forms alloys with the alkaline-earth metals.Berylliumis soluble in sodium only to the extent of a few atomic percent at approximately 800 °C (1,500 °F). Liquid sodium andmagnesiumare only partially miscible. The degree of solubility in sodium of the alkaline-earth metals increase...

Previously, some researchers studied the desilication effect of aluminum desilication agent, magnesium desilication agent, boron desilication agent and composite desilication agent on wheat straw pulp BKBL. The research mainly focused on the desilication efficiency of the desilication agent, and ...
The action of hydrochloric acid and, in a similar manner, that of sulfuric acid proceed slowly at room temperatures. However, a small input of heat accelerates the attack, which results in the formation of the lower chlorides and the mono-sulfate. These reactions are utilized in a similar man...
Bromine, sodium hydride, n-hexyl bromide, tetrakis(triphenylphosphine)pal- ladium (0) and anhydrous magnesium sulfate were purchased from Nakalai Tesque (Kyoto, Japan). Iodomethane, bis(1,5-COD) nickel (0), sodium sulfate and n-butyllithium in n-hexane solution (n-BuLi) were purchased from...
The residue was washed with 300 ml of water and extracted twice with 100 ml of dichloromethane. After the combined extract was dried over anhydrous magnesium sulfate, the solvent was evaporated. The residue was distilled three times under reduced pressure (Glass tube oven) by fractional disti...
