Will That Ionic Liquid Dissolve in Indian Group II?
QUILL/PETRONAS tuned alkyl chains for Group III+. Wear 2025 used PAO4. Most Indian volume is Group II. An IL that is brilliant in PAO and hazy in Group II is not a product. Solubility, then corrosion, then four-ball — in that order.

- QUILL/PETRONAS tuned alkyl chains for Group III+.
- Ionic liquids that dissolve in Group III/PAO often haze in Indian Group II. Solubility screens at 0 °C and after humidity aging belong in the first week of work, before tribology bragging.
- Name the test method on any number that reaches a TDS.
- Patents and papers are prior art, not a product Lubechem sells.
- Written for Indian blenders handed an IL sample from a European supplier.

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
India-specific science article. Makes Lubechem the adult in the IL conversation. 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; Wear 2025 206382; Lubechem Group I/II site guidance | 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 ionic liquid solubility Group II base oil 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 ionic liquid solubility Group II base oil 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 Indian blenders handed an IL sample from a European supplier 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.
