Title:
ヘビーナフサ中のケイ素元素の定量方法およびヘビーナフサの製造方法
Document Type and Number:
Japanese Patent JP7093207
Kind Code:
B2
Abstract:
To provide a method for quantitative measurement of silicon elements in naphtha with high accuracy.SOLUTION: The method for quantitative measurement of silicon elements in naphtha includes introducing a naphtha containing a silicon compound into an inductively-coupled plasma apparatus and atomizing the naphtha in a chamber controlled to a temperature of 10°C or less. The naphtha is introduced into the plasma to be atomized or ionized to quantitatively determine the amount of silicon atoms. Preferably, the naphtha comprises hexamethylcyclotrisiloxane as a silicon compound.SELECTED DRAWING: Figure 2
