Hi again, This request for PFC-318 is duplicated in your third e-mail (the one including carbon tetrafluoride).
Cheers, Roy. I have now retired but will continue to be active through an Emeritus Fellowship using this e-mail address. ________________________________ From: Dan Say <dan....@bristol.ac.uk> Sent: 29 March 2019 14:33 To: Lowry, Roy K.; cf-metadata@cgd.ucar.edu Subject: Re: New halocarbon standard name requests Apologies, can I also add the following: PFC-318 Standard name: mole_fraction_of_pfc318_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for pfc318 is c-C4F8. The IUPAC name for pfc318 is octafluorocyclobutane.

Here are the details of the proposed standard names. Proposal for a new standard variable names: Dichloromethane Standard name: mole_fraction_of_dichloromethane_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for dichloromethane is CH2Cl2. The IUPAC name is dichloromethane. Chloroform Standard name: mole_fraction_of_chloroform_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for chloroform is CHCl3. The IUPAC name for chloroform is trichloromethane. Perchloroethene Standard name: mole_fraction_of_perchloroethene_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for perchloroethene is CCl2CCl2. The IUPAC name for perchloroethene is tetrachloroethene. Carbon tetrachloride Standard name: mole_fraction_of_carbon_tetrachloride_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for carbon tetrachloride is CCl4. The IUPAC name for carbon tetrachloride is tetrachloromethane. Methyl chloroform Standard name: mole_fraction_of_methyl_chloroform_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for methyl chloroform is CH3CCl3. The IUPAC name for methyl chloroform is 1,1,1-trichloroethane. PFC-218 Standard name: mole_fraction_of_pfc218_in_air (Canonical unit: 1) Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y.
