Thermo-reversible self-healing polymeric coatings derived fromgum rosin
S Parihar, B Gaur - Progress in Organic Coatings, 2022
… The growing demand for the development of bio-based, greener and more
sustainable polymeric systems was the inspiration to develop two bio-based thermo-reversible
polymers derived from gum rosin, a product of pine trees, being reported in this …
Field Response of Black Turpentine Beetle to Pine Resin Oxidation and Pheromone Displacement
GA LeMay, T O'Loughlin, D Wakarchuk, J Hulcr - Journal of Chemical Ecology, 2022
… We mimicked natural terpene autooxidation processes by bubbling oxygen into
warm turpentine. The oxidation products are complex (Moore et al. 1956), but can be
grouped by their appearance at different stages of the oxidation process. Early in the …
This is interesting. One would think that oxidized turpentine would attract pine beetles, but not so.
Y Li, X Chen, L Wang, X Wei, M Nong, W Nong, J Liang - ACS Omega, 2022
The vapor–liquid equilibrium (VLE) of components of a turpentine + rosin system
were measured at 313.2 and 333.2 K using headspace gas chromatography. The
thermodynamic properties of the turpentine + rosin system such as activity …
Takes me back to my days at Princeton R & D when I was pretending to be an engineer and trying to figure out how to model the distillation of pine chemicals.

but biodiesel and biogasoline from tall oil pitch (TOP) is also produced there. ...
An interesting discussion of how the large Finnish oil refiner, Neste, has built a profitable biofuels business based on tall-oil pitch. Of course, the profit is really derived from the explicit and implicit subsidies provided by the government and the taxpayers.

This patent is really a long, detailed compendium of cannabinoids being mixed with many other incompatible compounds, i.e. adjuvants that can allow increased use in humans, moreso than would be possible if cannabinoids were mixed physically without adjuvants. The real question is how many cannabinoid- based mixtures actually work, and have FDA approvals.
Organic acid systems
United States Patent 11319479 B2 · Filed: 03/10/2020 · Published: 05/03/2022

Lee, Adrienne (Calgary, CA)
This patent deals with acid compositions and their employ in the oil recovery industry. There are some similarities to corrosion problems sometimes faced by PCA members in this patent. BTW, the use of terpenes is explained as a corrosion inhibition component.
METHODS OF KILLING NEMATODES COMPRISING THE APPLICATION OF AN ENCAPSULATED TERPENE COMPONENT
European Patent EP3659437 B1 · Filed: 01/24/2005 · Published: 05/04/2022
Assignee:
EDEN RESEARCH PLC (Oxfordshire OX14 4RQ, GB)
Inventors:
FRANKLIN LANNY (US)
OSTROFF GARY (US)
We are starting to see patents like this where terpenes are being encapsulated for application to destroy insect pests. And the use of terpenes to kill pernicious pests.
Composition to promote migration of acarids
United States Patent 11324209 B2 · Filed: 11/30/2018 · Published: 05/10/2022

Inventors:
Penninckx, Dorian (Woluwe-Saint-Lambert, BE)
Mailleux, Anne-catherine (Genval, BE)
This is a novel method to eliminate acarids without killing them with pesticides. Terpenes are used to get the insects to leave the premises, like giving the pests the bum’s rush.
