n-Butanol

What is n-Butanol

n-Butanol (n-butyl alcohol, 1-butanol; CAS 71-36-3) is a straight-chain primary aliphatic alcohol with the molecular formula C4H9OH and a molecular weight of 74.12 g/mol. It is a colorless, flammable liquid with a characteristic banana-like odor, a boiling point of 117.7 °C, and limited but significant miscibility with water (~7.7 g/100 mL at 20 °C). Industrially it is one of the most important C4 oxygenated solvents and chemical intermediates, used in the manufacture of butyl acrylate and methacrylate esters, glycol ethers, plasticizers (e.g., dibutyl phthalate), amino resins, and as a solvent in coatings, adhesives, and pharmaceuticals. The dominant commercial production route is the oxo process (hydroformylation) of propylene followed by hydrogenation, though the Reppe process and bio-based fermentation routes also exist.

1-Week Outlook, Updated: June 8, 2026 | Next Update: June 15, 2026

What's driving sentiment this week:

Past Week (2026-06-01 to 2026-06-07) — Sentiment: Bearish

Upstream feedstock costs rose with naphtha prices increasing 0.41% to USD 716.36/t on June 5, squeezing n-Butanol producer margins.

Demand weakened sharply as Chinese n-Butanol prices fell nearly 10% in May due to lack of support, exerting significant downward pressure on prices.

Supply chain signals remained neutral with stable petrochemical feedstock supply levels reported in the US through May 29.

This Week (2026-06-08 to 2026-06-14) — Outlook: Bearish

Price pressure will persist driven by high crude and naphtha costs limiting producer margins and preventing recovery in n-Butanol prices.

The key catalyst is the EIA Short-Term Energy Outlook on June 9 forecasting an 8.5 mb/d global oil inventory draw in Q2 2026, signaling sustained tight crude and feedstock availability.

A sudden easing of crude/naphtha supply or rapid demand pickup in China could reverse the bearish trend.

Key Market Impact

Rising feedstock costs and weak end-user demand are dominating price dynamics, pushing n-Butanol prices sharply lower since early June.

Refiners and buyers are likely cutting back purchases and operating closer to margin-neutral levels amid cost inflation and subdued consumption.

Substitutes & Alternatives

SubstituteReplacement Scenario / How It Substitutes
Isobutanol (2-methyl-1-propanol)Direct partial substitute in solvent applications (coatings, inks, adhesives) where the slightly lower boiling point (108 °C) and similar polarity are acceptable. Used as a drop-in or blend-in replacement in many industrial solvent formulations; also a feedstock alternative for butyl ester plasticizers and glycol ethers, though ester properties differ slightly. Requires reformulation review for regulated applications.
2-Ethylhexanol (2-EH)Substitutes n-butanol as the alcohol component in plasticizer manufacture (e.g., DEHP/DOP vs. DBP) when higher molecular weight and lower volatility are desired. In coatings, 2-EH-based glycol ethers can replace n-butyl glycol ethers where slower evaporation is beneficial. Not a drop-in for direct solvent use due to much higher boiling point (184 °C) and lower water miscibility.
n-Propanol (1-propanol)Can substitute n-butanol in solvent blends for coatings, cleaning agents, and pharmaceutical excipients where a lower-boiling, more water-miscible alcohol is acceptable. Requires reformulation to adjust evaporation rate and solvency. Not suitable as a plasticizer alcohol due to shorter chain length.
EthanolPartial substitute in solvent and cleaning applications, particularly where regulatory or bio-based preferences exist. Much higher water miscibility and lower boiling point (78 °C) mean it is not a direct drop-in; formulations must be redesigned. Used as a bio-based alternative in some surface coatings and personal care products where n-butanol's stronger solvency is not strictly required.
Butyl Cellosolve (2-butoxyethanol)Substitutes n-butanol as a coalescing solvent in waterborne coatings and cleaning products, offering better water compatibility and slower evaporation. It is a downstream derivative of n-butanol itself, but can be used where the ether-alcohol functionality provides superior performance. Requires formulation adjustment; not interchangeable in esterification reactions.
Methyl isobutyl ketone (MIBK)Substitutes n-butanol as an industrial solvent in nitrocellulose lacquers, extraction processes, and resin manufacture where a ketone solvent with similar boiling range (~116 °C) and moderate water miscibility is acceptable. Not suitable for esterification or as a plasticizer alcohol; requires reformulation and regulatory review for food-contact or pharmaceutical uses.
Bio-based n-Butanol (ABE fermentation)Chemically identical to petrochemical n-butanol and therefore a true drop-in substitute in all applications. Produced via Clostridium fermentation of sugars or starch. Substitution is driven by sustainability mandates, bio-content certification requirements, or supply diversification rather than technical performance differences. Currently at a cost premium vs. oxo-route n-butanol.
