Use a solvent blend that contains 1-methoxy-2,7-octadiene and an alkanols rather than the alkanols by itself to prepare a catalyst precursor suitable for use in butadiene telomerization.

Butadiene telomerization catalyst precursor preparation

A method of creating a library of standardized spectral data and identifying a sample by searching the standardized library for a match with the sample spectrum. The method entails determining and applying a transfer function which equalizes instrument bias between instruments and within the same instruments over time. A transfer function is specific to a particular instrument, and is based on the relationship between a reference spectrum of a standard as stored in a library and a spectrum of the standard obtained on the particular instrument of interest. This method provides enhanced library searching capabilities.

Method of creating standardized spectral libraries for enhanced library

A method of correcting for instrumental changes that influence the spectral response of a mass spectrometer over time. The method entails determining and applying a transfer function which equalizes instrument bias between mass spectrometers and within the same mass spectrometer over time. A transfer function is specific to a particular mass spectrometer, and is based on the relationship between a reference spectrum of a standard as stored in a library and a spectrum of the standard obtained on the particular mass spectrometer of interest. This method facilitates and simplifies recalibration, provides enhanced library searching capabilities for mass spectrometry, and may permit concentration determination from mass spectral data without the need to recalibrate an instrument with multiple standards.
