These acetophenone derivatives of mannich bases were synthesized by the reaction between the acetophenone, formaldehyde and alkanes(1). They were
evaluated for the analgesic, anti inflammatory and anticonvulsant activity. Phenytoin and its derivatives have shown good anticonvulsant activity by minimum
electro shock method. Indomethacin and its derivatives have shown good anti inflammatory activity by raw paw edema method. Indomethacin and its
derivatives have also shown good analgesic activity which can be observed by eddy’s hot plate method.
Key words: Mannich bases of acetophenone, anticonvulsant, and formaldehyde, anti-inflammatory.

Formaldehyde has been categorized as toxic, suspected carcinogen, teratogen and mutagen compound and widely applied in various industries. Millions ton of formaldehyde is yearly released into environments. Therefore, having enough information about this compound to control its environmental problems is necessary. Although, many articles about formaldehyde production, properties, removal and applications have been published, but access to all of this information in different data bases is not easy and a comprehensive review paper in this area is yet to be published. The aim of this paper is collecting information about toxicology, resources, productionand applications of formaldehyde. Formaldehyde canbe emitted into atmosphere from natural sources such as atmospheric reactions, fire forest,and biological metabolism. Anthropogenic sources are other important sources of formaldehyde emission. Collecting enough knowledge about common pollutants such as formaldehyde that have been frequently released into environment can make significant contributions to improving environmental quality.

During gas production from gas condensate reservoirs, as the bottom hole pressure drops
below the dew point pressure, the liquids drop out and form condensate banking resulting in significant loss of gas and condensate productivity. A new method for stimulating gas condensate
wells, is changing the rock wettability in near well-bore regions by chemical
treatments. In this study, a new chemical treatment was developed to alter the wettability
of carbonate rocks from water-wet to intermediate gas-wet in order to enhance gas relative
permeability. The treatment involves the use of an anionic fluoro-surfactant mixture with
an optimized concentration and a solvent. Contact angle and spontaneous imbibition
experiments were run to measure the wettability alterations. Scanning electron microscopy
(SEM), energy dispersive X-ray spectroscopy (EDAX) and adsorption isotherms were also
performed to monitor the amounts of surfactant solutions which were adsorbed on the rock surface. The increase in gas relative permeability was quantified by comparing the
permeability before and after chemical treatments. The contact angles were increased and
water and oil imbibitions were reduced significantly after the treatments. Finally, core
flood tests revealed that the optimized treatment could enhance the gas relative
permeability by a factor of 1.7 which demonstrated the ability in wettability alteration at
reservoir conditions.
