by 1898 the nishijin textile trade was well developed and encompassed the technology shared by the europeans. this marked a beginning of a new era of nishijin weaving and initiated the use of machinery in the japanese trade. nishijin has continued to have a successful textile industry throughout the years. today nishijin weaving is seen more frequently in japanese ceremonies, weddings being the most prominent. specifically, the traditional kimono for the bride is a work of art displaying the nishijin designs that have been handed down through generations of a family. these traditional designs range from scenes of nature, different breeds of birds and several different types of flowers. several other products, including kimono scarves, different types of kimonos, belts, shawls, many different types of cloth and decorations that adorn the walls of japanese homes, are also made using nishijin weaving.

alkylation occurs when a molecule replaces a hydrogen atom with an alkyl group that generally comes from an organic molecule. alkyl groups that are found naturally occurring in the environment are organometallic compounds. organometallic compounds generally contain a methyl, ethyl, or butyl derivative which is the alkyl group that replaces the hydrogen. other organic compounds, such as methanol, can provide alkyl groups for alkylation. methanol is found naturally in the environment in small concentrations, and has been linked to the release from biological decomposition of waste and even a byproduct of vegetation. the following reactions are alkylations of soluble compounds found in creosote preservatives with methanol.
