    1. INTRODUCTION The copolymerization of ethylene with 13-butadiene to give crystalline‚ homopolymer-free‚ high molecular weight‚ substantially linear copolymer is described. Butadiene polymerizes almost exclusively in a trans-14 structure‚ ranging in content from zero to 50 mole-%. At relatively low content of butadiene monomeric units (≤30 mole-%) X-ray crystallinity is of polyethylene type with a slight variation of the structural parameters. At higher levels of butadiene monomeric

    This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low yield at the

    In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser
