Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
Dimethylaminoethyl acrylate is a clear, colorless to slightly yellowish liquid with a pungent amine-like odor. It is miscible with water, reacts bases and hydrolyzes rapidly to acrylic acid and dimethylaminoethanol. It can form ignitable mixtures with air.
Independent control of solids retention time and hydraulic retention time: As all the biological solids are contained in the bioreactor, the solids retention time can be controlled independently from the hydrodynamic retention time. Small footprint: thanks to the membrane filtration, there is a high biomass concentration contained in a small ...
It is a hygroscopic, colorless, water-miscible liquid with a weak characteristic odor. It is the simplest 4-carbon lactone. It is mainly used as an intermediate in the production of other chemicals, such as N-methyl-2-pyrrolidone. [5] In humans, GBL acts as a prodrug for gamma-hydroxybutyric acid (GHB) and is often used as a recreational drug.
β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
It recommended instead that the effects of chemicals that cause similar adverse outcomes should be examined cumulatively. [42] Thus, the effect of phthalates should be examined together with other antiandrogens, which otherwise may have been excluded because their mechanisms or structure are different.
Groundwater: The water emerging from some deep ground water may have fallen as rain many tens, hundreds, or thousands of years ago. Soil and rock layers naturally filter the ground water to a high degree of clarity and often, it does not require additional treatment besides adding chlorine or chloramines as secondary disinfectants.
Aminomethyl propanol is used for the preparation of buffer solutions. [3] It is a component of the drugs ambuphylline and pamabrom.It is also used in cosmetics. [2]It is a precursor to oxazolines via its reaction with acyl chlorides. [5]
