Direct answer

RSC Sustainability (2024), with PETRONAS, reported boronium ILs with carboxylate anions, halide-free synthesis, no Zn/S/P, and solubility work in Group III+. That is the cleaner IL story versus FSI-anion grease patents. Solubility in Group II Indian base oils is the first experiment, not the four-ball.

  • RSC Sustainability (2024), with PETRONAS, reported boronium ILs with carboxylate anions, halide-free synthesis, no Zn/S/P, and solubility work in Group III+.
  • Task-specific boronium ILs (RSC Sustainability / QUILL–PETRONAS) are ashless additive prior art. Treat as a screening idea. Cost, hygroscopy and Group II solubility decide whether it ever sees a kettle.

Why ashless, halide-free matters

Why ashless, halide-free matters. RSC Sustainability (2024), with PETRONAS, reported boronium ILs with carboxylate anions, halide-free synthesis, no Zn/S/P, and solubility work in Group III+. That is the cleaner IL story versus FSI-anion grease patents. Solubility in Group II Indian base oils is the first experiment, not the four-ball.

Task-specific boronium ILs (RSC Sustainability / QUILL–PETRONAS) are ashless additive prior art. Treat as a screening idea. Cost, hygroscopy and Group II solubility decide whether it ever sees a kettle.

Literature/prior art for this note: RSC Sustainability 2024, D4SU00451E — task-specific boronium ILs as ashless additives (QUILL / PETRONAS). Read it as evidence under its own method, not as a formula you can paste onto an Indian CoA.

The reader is R&D teams chasing aftertreatment-safe antiwear. Search phrases around “ashless ionic liquid lubricant additive” should land on a decision: duty, method, purge, SKU sequence — then a link to the manufacturing page, not a second SOP.

Group III+ vs Group II solvency

Group III+ vs Group II solvency. RSC Sustainability (2024), with PETRONAS, reported boronium ILs with carboxylate anions, halide-free synthesis, no Zn/S/P, and solubility work in Group III+.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.

What this page is for

Contrasts with the FSI/PFAS IL grease patent. Shows Lubechem reads both sides of the IL literature. Images are labelled conceptual illustrations. Patents and papers are cited so you can go read them.

What the paper is evidence for — and what it is not

Paper says Useful to a plant Over-read
A mechanism or ranking under stated conditions Adds a test or a caution to the brief Not a drop-in Indian SKU
RSC Sustainability 2024, D4SU00451E — task-specific boronium ILs as ashless additives (QUILL / PETRONAS) Read the method section before the conclusion Do not market the DOI on a drum
Limited speed / load / oil Match your duty or discard Do not scale a ball-on-disc to a kiln girth gear
Additive name or treat A screening idea Treat rates in papers are not commercial packages

People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.

Questions plants actually ask

Is ashless ionic liquid lubricant additive a drop-in for whatever we run today?

Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.

Can we put ashless ionic liquid lubricant additive on the TDS because a patent or paper mentioned it?

No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.

Who owns the formula if Lubechem develops it?

Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.

What should R&D teams chasing aftertreatment-safe antiwear send in the first brief?

Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
