Castor is a star (Alpha Geminorum) of magnitude 1.6, the fainter star of the zodiacal constellationGemini, or the Twins. In 1719 it was discovered to be a visual binary star, with components of magnitudes 2.8 and 2.0 separated by 6 seconds of arc and revolving around each other in about 350 years. Each of these components has been found to be a spectroscopic binary. In addition, a faint companion, separated from the other two by 72 sec of arc, has been discovered. This star is also a spectroscopic binary, the two components of which revolve around each other in about one day. Hence, the entire system of the star Castor contains at least six stars. Its distance is about 45 light- years from the earth. Research Castor
Di(2-ethylhexyl) phthalate, also commonly called bis (2-ethylhexyl) phthalate, is a colourless, oily liquid with a slight odour. It was patented in 1933, and is primarily used as one of several plasticisers in polyvinyl chloride (PVC) resins for fabricating flexible vinyl products. These PVC resins have been used to manufacture teething rings, pacifiers, soft squeeze toys, balls, shower curtains, raincoats, adhesives, polymeric coatings, components of paper and paperboard, defoaming agents, enclosures for food containers, animalglue, surface lubricants, flexible devices for administering parenteral solutions, and other products that must stay flexible and uninjurious for their lifetime. It is also used to manufacture vinyl gloves used for medical examinations and surgery. As a non-plasticizer, di(2-ethylhexyl) phthalate is used as a replacement for polychlorinated biphenyls (PCBs) in dielectric fluids for electric capacitors. It is also used as a solvent in erasable ink, an acaricide for use in orchards, an inert ingredient in pesticides, a component of cosmetic products, and a vacuumpump oil; it is used to detect leaks in respirators and to test air filtration systems. Di(2-ethylhexyl) phthalate is insoluble in water, miscible with mineral oil and hexane, and soluble in most organic solvents. It is easily dissolved in body fluids such as saliva and plasma. Di(2-ethylhexyl) phthalate is a combustible liquid; it may burn, but does not readily ignite. It produces poisonous gas in a fire. When heated to decomposition, it emits acrid smoke. Di(2-ethylhexyl) phthalate is also known as bis(2-ethylhexyl) phthalate, bis(2- ethylhexyl)-1,2-benzenedicarboxylate, di(2-ethylhexyl)ortho-phthalate, di-sec-octyl phthalate, 2- ethylhexyl phthalate, NCI-c52733, disec-octyl phthalate, 1,2-benzenedicarboxylic acid, bis (2- ethylhexyl) ester, DOP, DEHP, and octoil.
