p-Menthadienes as Biorenewable Feedstocks for a Monoterpene-Based Biorefinery
biorefinery CST monoterpenes terpenes turpentine
2023/12/11
A terpene-based biorefinery is described that uses crude sulfate turpentine (CST) and gum turpentine (GT) to produce mixtures of p-menthadienes (p-MeDs) as biorenewable terpene feedstocks. An acid cat...

Factors affecting monoterpene emission from Chamaecyparis obtusa
biogenic emission seasonal variation vibration
2017/4/12
Monoterpenes are major compounds emitted by plants and contribute to the formation of photochemical oxidants and
secondary organic aerosols in the troposphere. We measured monoterpene emissions from ...
Value addition of essential monoterpene oil(s) in Geranium (Pelargonium graveolens) on leaf positions for commercial exploitation

2010/1/21
In this paper we propose the application of a mechanistic method for considering the seasonal dynamics of emission potential using the "Seasonal Isoprenoid synthase Model" (Lehning et al., 2001). We t...
VOC measurements within a boreal forest during spring 2005: on the occurrence of elevated monoterpene concentrations during night time intense particle concentration events
VOC measurements boreal forest monoterpene concentrations
2009/11/19
In this study we present measurements of selected trace gases and aerosols made in a boreal forest during the BACCI-QUEST IV intensive field campaign in Hyytiälä, Finland in April 2005. Spri...
Drought reduced monoterpene emissions from the evergreen Mediterranean oak Quercus ilex: results from a throughfall displacement experiment
monoterpene emissions evergreen Mediterranean oak Quercus ilex displacement experiment
2010/1/20
The effects of water limitations on the emission of biogenic volatile organic compounds are not well understood. Experimental approaches studying drought effects in natural conditions are still missin...
Process-based modelling of biogenic monoterpene emissions combining production and release from storage
Process-based modelling biogenic monoterpene emissions storage
2009/6/2
Monoterpenes, primarily emitted by terrestrial vegetation, can influence atmospheric ozone chemistry, and can form precursors for secondary organic aerosol. The short-term emissions of monoterpenes h...
