Abstract: During the final stages of Al(OH).sub.3 production, deliquoring the aluminum trihydroxide slurry of excess sodium ions in the form of caustic liquor is conventionally achieved by numerous water washes prior to drying the product. Addition of an effective amount of highly charged, high molecular weight anionic polymer flocculant to the aluminum trihydroxide slurry improves the filtration rate, i.e., increases the amount and rate of removal of caustic liquor from the slurry. Addition of the flocculant reduces the amount of washing necessary to remove sodium ions from the final cake and also provides higher cake solids which results in greater production per unit time and less expenditure of energy in the drying process. Anionic polymers derived from 80 to 100% of an anionic vinyl monomer such as acrylic acid and from 20 to 0% of a nonionic vinyl monomer such as acrylamide having molecular weights between 1.5 to 12.0.times.10.sup.6 are useful in deliquoring aluminum trihydroxide slurries.

Abstract: Superplasticizers for cementitious compositions are produced from a raw material mixture of (1) naphthalenesulfonic acid formaldehyde condensate and (2) free sulfuric acid using a 1-step process or a 2-step process. In the 1-step process, the mixture is neutralized with a zinc compound such as zinc oxide to a pH of about 2 to obtain a superplasticizer mixture of the free acid of the naphthalenesulfonic acid formaldehyde condensate and zinc sulfate. In the 2-step process, the mixture is first neutralized with a zinc compound such as zinc oxide to a pH of about 2 and then with a base such as sodium hydroxide to a pH of about 6 to obtain a superplasticizer mixture of the sodium salt of the naphthalenesulfonic acid formaldehyde condensate and zinc sulfate. These superplasticizer mixtures are superior to a low salt content commercial sodium salt of a naphthalenesulfonic acid formaldehyde condensate where sodium sulfate content has been reduced by lime treatment.
